1 Scope
NOTE This standard governs the selection, furnishing, and installation of finish hardware for swinging door openings, organized as numbered hardware sets, across commercial, institutional, and light-industrial occupancies. (1.1)
NOTE The opening is a coordinated assembly whose parts are specified by three complementary standards, and this is the hardware-only complement. The door leaf, the frame, gauges, cores, and fire-label assembly requirements are governed by
Doors Frames And Hardware for combined opening packages, by
Exterior Doors And Frames for exterior leaves, and by
Wood Doors for wood leaves. This standard is used when the hardware is specified separately from the door and frame manufacturing, which is common on larger projects where a hardware consultant authors the sets.
(1.2) 1.3Hardware sets shall be the organizing framework, with one numbered set assigned to each distinct opening type and every opening on the door schedule referencing exactly one set.
1.4Where a single opening is described by both this standard and a door or frame standard, the more specific requirement for that component shall govern, and conflicts shall be resolved by the Architect in writing.
1.5Electrified hardware items shall be specified in this standard at the product and hardware-set level only; their power supplies, conduit, raceway, and system programming are governed by Access Control Systems and shall be coordinated with that work and with Fire Alarm Systems. NOTE Related standards (1.6)
NOTE The following standards carry adjacent scope and are commonly coordinated with this work: (1.6.1)
2 Referenced Standards
2.1Hardware, materials, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited or a more recent edition is mandated by the authority having jurisdiction.
2.2Where referenced standards conflict, the more stringent requirement shall govern unless the Architect directs otherwise in writing.

3 Submittals
3.1 Action Submittals
NOTE The Contractor shall submit the following action submittals for review before fabrication or ordering of hardware: (3.1.1)
- Hardware schedule listing every opening, its assigned hardware set, and each item by manufacturer, product designation, function, finish, and quantity.
- Hardware sets, each numbered and cross-referenced to the openings it serves on the door schedule.
- Keying schedule showing the master-key hierarchy, keyed-alike groups, and the cylinder or core system.
- Manufacturer product data for each hardware item, including ANSI/BHMA grade, listing, and applicable certifications.
- Shop drawings or templates coordinating frame and door prep locations per DHI WDHS.3, including reinforcement for electrified items.
- Wiring diagrams and point-to-point riser for all electrified hardware, coordinated with access control and fire alarm.
- Samples of each finish on the actual hardware product where a finish match across manufacturers is required.
☑ Hardware schedule (opening-by-opening)
☑ Numbered hardware sets
☑ Keying schedule
☑ Manufacturer product data
☑ Frame/door prep templates (DHI WDHS.3)
☐ Electrified hardware wiring diagrams
☐ Finish samples on actual product
NOTE The Contractor shall submit the following informational submittals: (3.2.1)
- Certification or qualification of the hardware consultant authoring the sets, where one is engaged.
- Manufacturer listing documentation for fire exit hardware (UL 305 and UL 10C) and panic hardware (UL 305).
- Installer qualifications for electrified hardware.
☐ Hardware consultant qualification (AHC/DAHC)
☑ Fire exit hardware listing (UL 305 + UL 10C)
☑ Panic hardware listing (UL 305)
☐ Electrified hardware installer qualifications
3.3 Closeout Submittals
NOTE The Contractor shall submit the following closeout submittals before final acceptance: (3.3.1)
- Final keying schedule as keyed, with key bitting record delivered directly to the Owner under separate cover.
- Operation and maintenance manuals for each hardware type, including adjustment and lubrication instructions.
- Written record of door closer field adjustments, including measured opening force and sweep timing for ADA-path openings.
- Warranty documents for each hardware category.
☑ Final keying schedule and key bitting record
☑ Operation and maintenance manuals
☑ Door closer field-adjustment record (force and sweep)
☑ Warranty documents
4 Quality Assurance
NOTE On projects with 50 or more openings, significant electrified hardware, or complex keying hierarchies, a Certified Architectural Hardware Consultant (AHC or DAHC) adds value that far exceeds their fee: omitting the consultant shifts the entire coordination burden onto the General Contractor during submittals, reliably multiplies RFIs, and the cost of late frame rework and re-keying is many times the consultant's cost. (4.1)
4.2On projects of 50 or more openings, the hardware sets and schedule shall be prepared or reviewed by a Certified Architectural Hardware Consultant.
4.3The Contractor shall reconcile the hardware schedule against the door and frame schedule before any hardware is procured.
NOTE Frame prep for hinges, strikes, closers, and exit devices is punched in the shop when the frame is fabricated. A hardware change discovered after the frame is built requires field welding, a new frame, or a non-conforming workaround, so reconciliation must precede procurement. (4.3.1)
4.4The hardware installer for electrified items shall be trained and certified by the hardware manufacturer for the products installed.
4.5A pre-installation conference shall be held with the hardware supplier, installer, electrical contractor, and access control and fire alarm trades before frames are set.
NOTE Electric strikes, electrified locks, electrified exit devices, and electromagnetic hold-opens all require conduit, power supplies, and a fire-alarm interface that must be in the wall before the frame is set. Coordinating this after the rough-in is closed is a common and expensive miss. (4.5.1)
5 Hardware Sets and Grading
NOTE Hardware sets are the contract organizing unit, and the grade selected for each category sets the service life of the opening. (5.1)
NOTE Each numbered hardware set lists every item a given opening type requires, from hinges through the threshold, so that the schedule resolves an opening to a complete, procurable list. Grade 1 is the heavy commercial and institutional class under the ANSI/BHMA A156 series; Grade 2 is light commercial and residential; Grade 3 is residential. (5.1.1)
5.2Each opening shall be assigned exactly one numbered hardware set, and the set shall list every hardware item the opening requires.
5.3All hardware shall be Grade 1 per the applicable ANSI/BHMA A156 standard for commercial and institutional work, including IBC occupancy groups A, B, E, I, M, and R-1.
5.4Grade 2 hardware may be used only in light commercial single-tenant office space or residential common areas, and any such downgrade shall be documented in the hardware schedule.
NOTE Specifying Grade 2 locksets or closers to save cost in assembly, educational, or healthcare occupancies produces premature failure under high cycle counts. The savings are recovered as warranty calls and early replacement within the first few years. (5.4.1)
● Grade 1 (heavy commercial / institutional)
○ Grade 2 (light commercial / residential common areas)
● Yes, Certified Architectural Hardware Consultant (AHC/DAHC)
○ No, architect-self-specified
6 Hinges and Pivots
NOTE Hinges carry the entire weight and cycle load of the leaf, and their type, weight, and count are selected from door size, frequency, and rating. (6.1)
NOTE A standard-weight ball-bearing butt hinge serves doors up to 3 ft wide and under roughly 175 lb at normal traffic. A heavy-weight hinge with a thicker leaf is used for heavier leaves or high-frequency openings. A continuous (full-height) hinge distributes load along the entire edge for high-cycle or high-abuse openings and eliminates the sag point of a butt hinge. (6.1.1)
6.2Butt hinges shall be ball-bearing type, Grade 1 per ANSI/BHMA A156.1.
6.3Standard-weight hinges (0.134 in leaf) shall be used for doors up to 3 ft wide weighing less than 175 lb at normal traffic frequency.
6.4Heavy-weight hinges (0.180 in leaf) shall be used for doors over 175 lb or openings exceeding 400 cycles per day.
6.5Continuous geared or pin-and-barrel hinges shall be used where the schedule designates high-cycle or high-abuse openings.
6.6A minimum of three hinges shall be provided for doors up to 90 in tall, and a fourth hinge shall be added for each additional 30 in of door height.
6.7A minimum of three hinges shall be provided on all fire-rated openings regardless of height, per NFPA 80.
6.8Hinges on out-swinging exterior or secured doors shall have non-removable pins (NRP) or a security stud.
● 4.5 x 4.5 standard-weight ball-bearing butt (0.134 in leaf)
○ 4.5 x 4.5 heavy-weight ball-bearing butt (0.180 in leaf)
○ Continuous (full-height geared) hinge
○ Spring hinge (self-closing)
● 3 (door up to 90 in tall)
○ 4 (door 90-120 in tall)
○ 5 (door over 120 in tall)
● Standard pin
○ Non-removable pin (NRP)
○ Security stud
7 Locksets and Latchsets
NOTE The lockset format and function together define how an opening is secured and operated, and the function must match the room's use. (7.1)
NOTE A cylindrical (bored) lockset fits a bored door prep and is the workhorse of commercial interiors; a mortise lockset uses a rectangular case let into the door edge and offers heavier duty, more functions, and integral deadbolt options at higher cost. Function names — passage, privacy, classroom, storeroom, office, dormitory, communicating, entrance — describe exactly which side latches, locks, or unlocks, and are selected per room, not per door type. (7.1.1)
7.2All locksets shall be Grade 1 per ANSI/BHMA A156.2 for bored locksets and per ANSI/BHMA A156.13 for mortise locksets.
7.3Lever or loop trim shall be provided on all locksets and latchsets; knobs shall not be used.
NOTE ICC A117.1 requires operable hardware that does not require tight grasping, pinching, or wrist twisting. A lever or loop handle satisfies this; a round knob does not and is non-compliant on accessible openings. (7.3.1)
7.4The lock function for each opening shall match the room use designated on the schedule, and a function not on the standard list shall not be substituted without the Architect's approval.
7.5Mortise locksets shall be used where the schedule designates heavy-duty service, integral deadbolt, or a function not available in a cylindrical case.
7.6Lever return shall be within 1/2 in of the door face to prevent catching clothing or wheelchair components.
● Cylindrical / bored (ANSI/BHMA A156.2 Grade 1)
○ Mortise (ANSI/BHMA A156.13 Grade 1)
Passage (no lock)
Privacy (bath/bedroom)
Office (lockable from inside)
Classroom (key-locked outside trim)
Storeroom (always-locked outside, free egress)
Entrance
Communicating
● Lever (ADA-compliant)
○ Loop / return-to-door (ADA-compliant)
8 Exit Devices
NOTE Exit devices provide single-operation egress under load, and the distinction between panic hardware and fire exit hardware is a life-safety boundary that drives both listing and dogging. (8.1)
NOTE Panic hardware is listed to UL 305 for egress-only openings and may be mechanically dogged to hold the latch retracted. Fire exit hardware is listed to both UL 305 and UL 10C and is required on fire-rated openings, where it must positively latch on every cycle. Specifying panic hardware on a fire-rated opening, or leaving mechanical dogging enabled on a fire door, is a code defect that fails inspection. (8.1.1)
8.2Exit devices shall be Grade 1 per ANSI/BHMA A156.3.
8.3Panic hardware shall be provided on egress doors in assembly (A) and educational (E) occupancies with an occupant load of 50 or more.
8.4Panic hardware shall be provided on all egress doors in high-hazard (H) occupancies regardless of occupant load.
8.5Fire exit hardware listed to both UL 305 and UL 10C shall be provided on all fire-rated egress openings.
8.6Mechanical dogging shall not be provided on fire-rated openings; cylinder dogging or electric latch retraction shall be used where the schedule requires the latch held retracted on a fire door.
8.7The exit device type shall match the door and frame prep, and the device type shall not be changed against an already-fabricated frame without re-prepping or replacing the frame.
NOTE Rim devices need a frame-mounted rim strike; mortise devices need a mortise prep; surface and concealed vertical-rod devices need top and bottom preps. Substituting one type for another after the frame is built is a major RFI and often a frame replacement. (8.7.1)
8.8Exit device operating force shall not exceed 15 lbf to release the latch, per NFPA 101 and IBC Section 1010.
8.9Exit device touchpad or crossbar shall be mounted between 34 in and 48 in above the finished floor, per ICC A117.1.
● Rim (single-point, surface)
○ Mortise (multi-point with mortise case)
○ Surface vertical rod (SVR)
○ Concealed vertical rod (CVR)
● Panic hardware (UL 305) - non-rated opening
○ Fire exit hardware (UL 305 + UL 10C) - rated opening
○ Mechanical dogging (non-rated only)
○ Cylinder dogging
○ Electric latch retraction
● None (positive latching, rated opening)
9 Door Closers and Hold-Opens
NOTE Closers control the swing for both safety and accessibility, and the mounting, force, and timing must be set in the field to meet ADA limits. (9.1)
NOTE A surface-mounted closer mounts to the door or frame face in a regular-arm, top-jamb, or parallel-arm configuration; a concealed overhead closer hides in the frame head; a floor closer carries heavy or high-traffic leaves from below. The parallel-arm and top-jamb mountings produce different opening-force results from the same closer, so the configuration matters to ADA compliance and must be verified after installation. (9.1.1)
9.2Door closers shall be Grade 1 per ANSI/BHMA A156.4.
9.3The closer mounting configuration shall be selected to suit the door swing, frame condition, and the required opening force, and shall be shown on the hardware set.
9.4Closer sweep speed shall be adjusted so the door takes a minimum of 5 seconds to move from 90° to 12° from the latch, per ICC A117.1.
9.5Closer latch speed shall be adjusted to seat the door without slamming, typically within 0 to 3 seconds.
9.6Closer backcheck should be set to engage at approximately 70° of opening to protect adjacent walls and the door from over-swing.
9.7Interior hinged doors on accessible routes shall be adjusted so the opening force does not exceed 5 lbf, per ICC A117.1.
NOTE The 5 lbf interior limit does not apply to exterior doors or fire-rated doors, which require a higher closing force to latch reliably and are exempt. (9.7.1)
9.8Electromagnetic hold-opens shall be fail-safe and shall release the door to the closed position on a signal from the fire alarm system, coordinated with Fire Alarm Systems. 9.9Door closer opening force and sweep timing shall be measured and recorded at final inspection for every accessible-path opening.
● Surface-mounted, parallel arm
○ Surface-mounted, top jamb
○ Surface-mounted, regular arm
○ Concealed overhead
○ Floor closer / pivot closer
● None
○ Mechanical hold-open (non-rated only)
○ Electromagnetic hold-open, fail-safe (FA release)
10 Stops, Holders, and Protection Plates
NOTE Stops, holders, and plates protect the door, the wall, and the finish from the wear of daily use. (10.1)
NOTE A wall stop or floor stop arrests the swing before the lever strikes the wall; a magnetic holder parks the door open where the schedule allows; kick, mop, and armor plates take the abuse at the base; push and pull plates protect the face of doors without a lockset. (10.1.1)
10.2A door stop shall be provided at every opening to arrest the swing before the trim contacts the wall.
10.3Wall stops shall be installed only where solid blocking or backing exists in the wall, coordinated with Gypsum Board Assemblies; a floor stop or overhead stop shall be used where backing is absent. 10.4Kick plates shall be provided on the push side of doors subject to cart, foot, or equipment traffic, sized to 2 in less than the door width and 10 in high unless otherwise scheduled.
10.5Mop plates shall be provided at the base of doors in wet-cleaned areas.
10.6Push and pull plates shall be provided on doors without a lockset where hand contact is expected on a finished face.
10.7Overhead stops or holders shall be specified where a wall or floor stop is not feasible and the swing must be limited.
● Wall stop (requires backing)
○ Floor stop (dome or rod)
○ Overhead stop / holder
☑ Kick plate (push side)
☐ Mop plate (wet areas)
☐ Armor plate (high abuse)
☐ Push plate
☐ Pull plate
11 Thresholds, Weatherstripping, and Gasketing
NOTE The threshold and seal package controls air, water, smoke, and sound at the opening perimeter, and ADA limits the threshold profile a wheelchair must cross. (11.1)
NOTE A threshold seals and transitions the floor at the opening; weatherstripping at the head and jambs and a sweep or automatic door bottom at the base complete the seal. Smoke seals are required on smoke-rated assemblies, acoustic seals on sound-rated assemblies, and weather seals on exterior openings. A sound-rated door needs both perimeter gasketing and an automatic door bottom to reach its rated STC. (11.1.1)
11.2Thresholds shall comply with ANSI/BHMA A156.21 and gasketing shall comply with ANSI/BHMA A156.22.
11.3Thresholds on accessible routes shall not exceed 1/2 in in total height, per ICC A117.1.
11.4Any vertical face of a threshold on an accessible route shall not exceed 1/4 in in height.
11.5The remainder of a threshold rise above 1/4 in shall be beveled at a slope no steeper than 1:2.
11.6Smoke-rated openings shall be provided with listed smoke-seal gasketing at the head, jambs, and meeting stiles.
11.7Exterior openings shall be provided with full perimeter weatherstripping and a door bottom seal appropriate to the sill condition.
11.8Sound-rated openings shall be provided with both perimeter acoustic gasketing and an automatic door bottom.
NOTE Omitting the automatic door bottom on a sound-rated assembly is a frequent miss that is only discovered during testing and balancing or acoustic commissioning, after the opening is installed. (11.8.1)
11.9The door bottom type shall be selected to suit the sill, with an automatic (drop-seal) door bottom where a continuous sill seal is required and a surface sweep where a threshold-only seal is adequate.
○ None (interior, non-rated)
● Smoke seal (smoke-rated)
○ Acoustic seal (sound-rated)
○ Weather seal (exterior)
● None
○ Surface sweep
○ Automatic (drop-seal) door bottom
12 Pair Hardware: Coordinators and Flushbolts
NOTE Pairs of doors need extra hardware so the leaves close and latch in the correct order. (12.1)
NOTE A coordinator forces the inactive leaf to close before the active leaf so an astragal or overlapping edge seats correctly. Flushbolts secure the inactive leaf top and bottom; automatic flushbolts release when the active leaf opens and are required on fire-rated pairs without a mullion. (12.1.1)
12.2A coordinator shall be provided on pairs with an astragal or overlapping edge where the leaves must close in sequence.
12.3Automatic or constant-latching flushbolts shall be provided on the inactive leaf of fire-rated pairs that do not use a removable mullion.
12.4A removable mullion may be used in place of vertical-rod or flushbolt hardware on rated pairs where the schedule permits.
● Removable mullion with rim devices
○ Vertical-rod devices on both leaves
○ Active leaf device with flushbolts on inactive leaf
13 Finishes
NOTE Finish is specified by the BHMA designation and matched across every item in a set so the opening reads as one. (13.1)
NOTE The 600-series numbers (626, 630, 613) are the current ANSI/BHMA A156.18 designations that replaced the older US designations (US26D, US32D, US10B); both still appear in practice and should be listed together. Mixing finish sources without a sample submittal produces visible variation between, for example, hinges from one maker and locksets from another. (13.1.1)
13.2All hardware finishes shall comply with ANSI/BHMA A156.18 and shall be specified by both the BHMA 600-series number and the corresponding US designation.
13.3Finishes shall be matched across all items within a hardware set, and a finish match between items from different manufacturers shall be verified by a sample submittal.
13.4Where a project finish is not designated, satin chromium (US26D / 626) shall be the default for interior hardware and satin stainless steel (US32D / 630) for exterior or high-moisture openings.
Satin chromium US26D / 626 (interior default)
Satin stainless steel US32D / 630 (exterior / high-moisture)
Oil-rubbed bronze US10B / 613 (institutional / hospitality)
Satin brass US4 / 606
Bright stainless steel US32 / 629
14 Keying and Cylinders
NOTE The keying plan defines who can open what, and it must be designed with the Owner before submittals or the contractor inherits a design problem. (14.1)
NOTE Cylinders may be keyed alike within a group, master-keyed so one key opens many openings, or grand-master-keyed across master groups. An interchangeable core (SFIC or LFIC) lets the Owner re-key without removing the lock, but cores are manufacturer-proprietary, so a core brand that differs from the Owner's existing system forces a facility-wide re-key. (14.1.1)
14.2Cylinders and input devices shall comply with ANSI/BHMA A156.28.
14.3A complete keying schedule shall be developed with the Owner before hardware submittals, establishing master-key levels, keyed-alike groups, and the cylinder or core system.
NOTE A hardware specification without a keying plan forces the contractor to author the keying design during submittals, which is outside their scope and a common source of schedule delay. The Owner must be engaged at the design stage. (14.3.1)
14.4Where interchangeable cores are specified, the core format and keyway shall match the Owner's existing master-key system.
NOTE Selecting an SFIC core brand different from the Owner's existing cylinders requires re-keying the entire facility to a single system, which is rarely the intent and always costly. The existing system must be confirmed before the core brand is chosen. (14.4.1)
14.5Keys shall be stamped "Do Not Duplicate" only where the Owner directs, and a restricted or patented keyway shall be used where key control is required.
14.6The key bitting record shall be delivered directly to the Owner under separate cover and shall not be included in general closeout documents.
○ Keyed alike (single group)
● Master-keyed
○ Grand-master-keyed
○ Construction keying with Owner change-over
○ Conventional cylinder
● Small-format interchangeable core (SFIC)
○ Large-format interchangeable core (LFIC)
○ Restricted / patented keyway
● Owner-keyed (factory to Owner system)
○ Contractor-keyed with Owner change-over
15 Electrified Hardware
NOTE Electrified items add access control and remote release at the opening, and the fail mode must match whether the door is on an egress path or secures an asset. (15.1)
NOTE A fail-safe device unlocks when power is removed and is required on egress doors and on fire-alarm-released hold-opens, so people are never trapped on a power loss. A fail-secure device locks when power is removed and is appropriate for protecting a secure room. Choosing the wrong mode is a life-safety defect on egress and a security defect on a secured opening. (15.1.1)
15.2Electrified hardware shall be specified at the product and hardware-set level in this standard; power supplies, conduit, and system programming are governed by Access Control Systems. 15.3Egress openings and electromagnetic hold-opens shall use fail-safe devices that release on loss of power or on a fire-alarm signal.
15.4Secured openings that are not on an egress path may use fail-secure devices that remain locked on loss of power.
15.5Electrified hardware shall operate at 24VDC unless a specific item requires 12VDC, and the power supply VA rating shall be verified against the connected hardware load.
NOTE 24VDC is preferred over 12VDC because it draws less current and tolerates the voltage drop of longer wire runs, which matters as door count and run length grow. (15.5.1)
15.6Power transfer to the door leaf shall be provided by a concealed electric hinge, an electric power-transfer device, or a door loop, coordinated with the door and frame prep.
None
Electric strike
Electrified mortise lock
Electrified cylindrical lock
Electrified exit device (electric latch retraction)
Electromagnetic hold-open
● Fail-safe (de-energize to unlock) - egress / hold-open
○ Fail-secure (de-energize to lock) - secured non-egress
16 Installation
NOTE Correct installation locations and adjustments are what make compliant hardware actually perform, and the DHI template governs the prep. (16.1)
NOTE DHI WDHS.3 fixes the standard locations: the top hinge 5 in from the head of the door, the bottom hinge 10 in from the floor, and additional hinges evenly spaced between. These locations must match the shop frame prep, so the template controls coordination, not field judgment. (16.1.1)
16.2Hardware shall be installed in the locations established by DHI WDHS.3 and the approved frame prep templates.
16.3The top hinge shall be located 5 in from the head of the door and the bottom hinge 10 in from the floor, with intermediate hinges evenly spaced.
16.4Lockset and lever centerlines shall be mounted between 34 in and 48 in above the finished floor, per ICC A117.1.
16.5Lockset and lever centerlines should be mounted between 38 in and 44 in above the finished floor as the standard installed range.
16.6Door viewers shall be mounted at 60 in above the finished floor, with an additional accessible viewer at 48 in where an accessible viewer is required.
16.7Fire door hardware shall be installed without field modifications prohibited by NFPA 80, and no holes shall be cut in a fire door or frame beyond those permitted by the listing.
16.8Door closers shall be adjusted in the field for sweep speed, latch speed, backcheck, and opening force after the door and frame are fully installed.
16.9Electrified hardware shall be installed, terminated, and functionally tested by the manufacturer-certified installer.
16.10Hardware shall be installed only after painting and finishing of the door and frame are substantially complete to avoid finish damage.
17 Field Quality Control
NOTE Every opening is verified for operation, force, and life-safety function before acceptance. (17.1)
17.2Each opening shall be operated through a full cycle to confirm the latch, lock, closer, and seals function as specified.
17.3Opening force and closer sweep timing shall be measured and recorded for every accessible-path opening, and any opening exceeding the ADA limits shall be re-adjusted.
17.4Fire-rated openings shall be tested for positive latching and proper closing on every cycle, and any opening that fails to latch shall be corrected before acceptance.
17.5Electrified hardware shall be functionally tested with the access control and fire alarm systems to confirm correct fail-safe or fail-secure operation and fire-alarm release.
17.6Fire door assemblies shall be functionally inspected annually after acceptance, per NFPA 80, with results documented and retained by the Owner.
18 Delivery, Storage, and Handling
18.1Hardware shall be delivered in the manufacturer's original packaging, individually marked with the opening number and hardware set it serves.
18.2Hardware shall be stored in a clean, dry, secure area and protected from weather, dust, and theft until installation.
18.3Keys and cores shall be kept under the Owner's or hardware supplier's secure control and shall not be left at the installation area.
19 Warranty
19.1Door closers shall carry a manufacturer warranty against defects in material and workmanship for a minimum of 10 years.
19.2Exit devices and locksets shall carry a manufacturer warranty for a minimum of 3 years.
19.3Electrified hardware shall carry a manufacturer warranty for a minimum of 1 year, or the longer period offered by the manufacturer.
19.4All other finish hardware shall carry the manufacturer's standard warranty, and warranty documents shall be delivered at closeout.
● 10 years
○ 25 years
○ 30 years
20 Spare Parts
NOTE The Owner shall be furnished with spare keys and maintenance items so the facility can be operated and serviced after handover. (20.1)
20.2The Contractor shall furnish spare keys in the quantity established by the keying schedule, delivered directly to the Owner.
20.3The Contractor shall furnish a maintenance kit of closer adjustment tools, spring cartridges, and seal stock as recommended by the manufacturer.
☑ Spare keys per keying schedule
☑ Closer adjustment tools
☐ Spare seal / gasket stock
☐ Spare interchangeable cores
