1 Scope
NOTE This standard covers the furnishing and installation of factory-fabricated metal lockers and their trim, accessories, and anchorage. (1.1)
NOTE A metal locker is an assembly of formed steel sheet — a body (back, sides, top, and bottom), a door, and a door frame — joined either by mechanical fasteners (knocked-down, or KD, construction) or by welding, and finished with a baked powder-coat enamel. (1.2)
NOTE The scope includes the selection of construction grade to match the service duty, the steel gauges of each component, the ventilation type appropriate to the contents stored, the latching and locking method, the trim and accessories that finish a locker installation, the dimensional and operational requirements for accessible lockers, and the anchorage and seismic restraint of the installed run. (1.3)
NOTE This standard establishes the material, construction, finish, hardware, accessibility, and installation requirements for the lockers shown on the locker drawings. (1.4)
NOTE The single most consequential decision in this standard is matching the construction grade to the service duty. (1.5)
NOTE A standard-duty KD locker that performs adequately in a supervised employee coat room will be pried, dented, and racked out of service within a season in an unsupervised school corridor or a high-turnover athletic locker room. (1.6)
NOTE The narrative below ties each construction grade and gauge to the occupancy and abuse level in which it is the appropriate choice, so that the specifier selects the locker from the actual service environment rather than from first cost alone. (1.7)
NOTE Plastic, polymer, and phenolic lockers are an alternative to steel where moisture, corrosion, or hose-down cleaning rules steel out; those materials are addressed in
Plastic Lockers and are noted here only as a selection branch.
(1.8) 1.11This work shall be coordinated with the flooring and base trades for the floor condition beneath closed and Z bases.
1.13This work shall be coordinated with the electrical trade where electronic locks require power or network connection.

☐ Attic-stock locks, number plates, and touch-up paint inventory
3.2.2At substantial completion the Contractor shall provide the manufacturer's care and maintenance instructions, the manufacturer's written warranty, a master keying schedule or combination/programming record for the installed locks, and an inventory of attic-stock parts (number plates, locks, and touch-up paint) where specified.
3.2.3Lock control documentation shall be transmitted directly to the Owner's designated representative and shall not be left with the lockers.
4 Quality Assurance
4.1 Manufacturer Qualifications
4.1.1The manufacturer shall be a firm regularly engaged in the fabrication of metal lockers of the type, construction grade, and lock specified, with a minimum of five years of production experience and products in service in comparable applications.
4.1.2Lockers, trim, accessories, and locks within a single installation shall be the product of a single manufacturer to ensure dimensional fit and finish match.
4.2 Single-Source Responsibility
NOTE Trim, fillers, sloped tops, and bases are fabricated to the manufacturer's locker module and frame profile; mixing trim from one manufacturer with lockers from another produces misaligned joints and exposed gaps. (4.2.1)
NOTE Locks are machined to the manufacturer's door and frame preparation. (4.2.2)
○ All lockers, trim, accessories, and locks from a single manufacturer
○ Lockers and accessories furnished as a coordinated package by a single supplier
4.2.3The locker body, door, frame, trim, and lock shall be a matched system from one source.
4.3 Field Measurements
NOTE Bank lengths, recess depths, soffit heights, and the as-built location of walls and columns determine the number of lockers, the trim, and the filler panels required. (4.3.1)
4.3.2The Contractor shall verify field dimensions at each locker location before fabrication.
4.3.3Where field conditions differ from the contract drawings, the Contractor shall notify the Architect before fabrication so that openings, trim, and fillers can be adjusted.
5 Materials
5.1 Steel Sheet
○ Cold-rolled carbon steel sheet (ASTM A1008), standard dry interior
○ Galvannealed steel sheet (ASTM A653), elevated humidity / intermittent moisture
5.1.1Locker components shall be formed from prime, commercial-quality mild steel sheet, free of surface imperfections.
5.1.2Cold-rolled sheet shall conform to ASTM A1008/A1008M.
5.1.3Where hot-rolled sheet is used for heavier structural members, it shall conform to ASTM A1011/A1011M.
5.1.4Where lockers will be exposed to elevated humidity or intermittent moisture, zinc-coated (galvannealed) sheet conforming to ASTM A653/A653M shall be specified for the body and door so that the steel substrate resists corrosion at coating defects.
5.2 Component Gauges by Construction Grade
NOTE The steel gauge of each component is the physical measure of locker duty. (5.2.1)
NOTE Gauge is expressed as a sheet-metal gauge number, where a lower number is a thicker, heavier sheet. (5.2.2)
NOTE The body, door, and frame each carry a gauge appropriate to the construction grade; the door and the frame — the components that take direct abuse — are heavier than the body in every grade. (5.2.3)
NOTE The values below are the procurable standards across the major manufacturers for each grade. (5.2.4)
NOTE Standard-duty KD lockers ship as flat components fastened together in the field. (5.2.5)
NOTE They are the economical choice for supervised, low-abuse employee, office, and light-commercial applications. (5.2.6)
NOTE Standard-duty bodies are typically 24-gauge with 16-gauge door frames and 16-gauge doors. (5.2.7)
NOTE Heavy-duty KD lockers use heavier body and door sheet and reinforced frames while retaining field-assembled KD construction. (5.2.8)
NOTE They are the appropriate selection for school corridors and general institutional use. (5.2.9)
NOTE Heavy-duty bodies are typically 16-gauge with 14- or 16-gauge door frames and 14- or 16-gauge doors. (5.2.10)
NOTE Welded (fully assembled) lockers arrive as rigid, factory-welded units with no field-fastened body seams to loosen, racking-resistant frames, and the highest abuse resistance. (5.2.11)
NOTE They are the appropriate selection for athletic and team locker rooms, public recreation, corrections, and any environment with heavy abuse or no supervision. (5.2.12)
NOTE Welded bodies are typically 16-gauge with 12- or 14-gauge frames and 14- or 16-gauge doors. (5.2.13)
Standard-duty knocked-down (KD) — supervised, low-abuse employee/office
Heavy-duty knocked-down (KD) — school corridor, general institutional
Welded — athletic/team room, recreation, corrections, high-abuse
○ 24 gauge (standard-duty)
○ 16 gauge (heavy-duty / welded)
○ 16 gauge (standard / heavy-duty)
○ 14 gauge (heavy-duty)
○ 12 gauge (welded high-abuse)
○ 16 gauge (standard / heavy-duty)
○ 14 gauge (heavy-duty / welded)
5.2.14The construction grade shall be selected to match the service duty: standard-duty KD for supervised low-abuse employee and office use, heavy-duty KD for school corridors and general institutional use, and welded for athletic and team rooms, recreation, corrections, and any high-abuse or unsupervised environment.
5.2.15Standard-duty lockers shall not be specified for unsupervised school corridors, athletic rooms, or any high-abuse application.
5.2.16Door frame vertical members shall form a continuous integral door strike the full height of the opening.
5.2.17KD body seams shall be flanged to provide a double thickness of metal at joints and corners.
5.3 Finish
NOTE The five-stage (or better) pretreatment — clean, rinse, iron- or zinc-phosphate conversion, rinse, seal — is essential: powder coat applied over unphosphatized steel loses adhesion and the finish fails at the first impact or scratch. (5.3.1)
Low gloss / matte (hides scratches and fingerprints, athletic/corridor)
Medium / satin gloss
High gloss
2501000
2505007501000
Default: 500 h
Manufacturer's standard color (single, as selected)
Two-tone (body one color, doors another)
Custom color match (extended lead time)
5.3.2Lockers shall be finished with a baked thermoset powder-coat enamel electrostatically applied over a cleaned, phosphatized steel substrate.
5.3.3The cured finish shall meet the performance requirements specified below.
5.3.4Finish adhesion shall be not less than rating 4B when tested per ASTM D3359 (cross-cut tape test).
5.3.5Finish corrosion resistance shall show no more than minimal undercutting at a scribe after 500 hours of salt-spray exposure per ASTM B117.
5.3.6Finish impact resistance shall show no cracking or loss of adhesion at 80 in-lb direct impact per ASTM D2794.
6 Locker Types and Configuration
6.1 Tier Arrangement
NOTE The tier arrangement is the number of separately locking openings stacked within one locker frame height. (6.1.1)
NOTE More tiers give more openings per floor area at the cost of opening height. (6.1.2)
NOTE A single tier (one-tier) is one full-height opening per frame, suited to hanging coats and street clothes, and is the standard for employee and corridor lockers where garments are stored. (6.1.3)
NOTE A double tier (two-tier) stacks two openings, each roughly half the frame height — a common school-corridor configuration that doubles locker count where full-height hanging space is not required. (6.1.4)
NOTE A triple tier (three-tier) stacks three openings and is used where user count is high and stored items are small (gym clothes, books, personal effects). (6.1.5)
NOTE A box tier (four-, five-, or six-tier) provides four or more compact openings per frame for personal-item, valet, and day-use storage where many users share a small footprint. (6.1.6)
NOTE A Z-tier provides two interlocking Z-shaped openings per width, each giving partial hanging height at roughly half the floor area of a single-tier locker — a space-efficient compromise that still allows short garments to hang. (6.1.7)
Single tier (one-tier) — full-height, hanging garments
Double tier (two-tier)
Triple tier (three-tier)
Box tier (four/five/six-tier) — compact personal items
Z-tier — interlocking, partial hanging height, space-efficient
6.1.8Tier shall be selected for the contents and the user: full-height single tier for hanging garments and street clothes, and box or triple tier for compact personal-item storage and high user counts.
6.2 Opening Size
NOTE The values below are the common procurable nominal sizes and serve as datasheet defaults where the drawings do not dictate otherwise. (6.2.1)
924
912151824
Default: 12 in
1224
1215182124
Default: 15 in
6.3 Ventilation
NOTE Non-ventilated solid doors are appropriate only for dry storage of non-perishable items. (6.3.1)
Solid (non-ventilated) — dry storage only
Louvered door (general athletic/gym ventilation)
Full-perforated door (high airflow, wet team rooms)
Diamond-perforated door and sides (maximum airflow, pool/aquatic)
6.3.3Lockers that store damp athletic clothing, footwear, or wet-weather garments shall be ventilated so that moisture and odor are not trapped.
6.3.4The ventilation type shall be matched to the airflow needed: louvered doors for general athletic and gym use, and full perforation or diamond perforation for maximum airflow in wet team rooms and pool environments.
6.3.5Louvers and perforations shall be formed in the door (and, for diamond ventilation, the sides) without sharp edges.
7 Latching and Locking
NOTE The latching mechanism holds the door closed and engages the lock; the lock secures the contents. (7.1)
NOTE The two are selected together. (7.2)
NOTE Recessed handles and recessed latches reduce snag and vandalism in corridors and athletic rooms; surface lift handles are simpler and lower cost for supervised employee use. (7.3)
NOTE Multi-point latching distributes the holding force along the door height and resists prying in abuse-prone applications. (7.4)
7.5 Latch and Handle
NOTE Three-point (multi-point) latching engages the door at the top, center, and bottom of the frame and is the standard for unsupervised corridor and athletic lockers because it resists the pry-at-a-corner attack that defeats single-point latches. (7.5.1)
NOTE The recessed handle houses the lock in a protected pocket so the lock body cannot be struck or pried. (7.5.2)
Recessed handle, single-point latch (low-abuse, recessed lock pocket)
Recessed handle, three-point latch (corridor/athletic, anti-pry)
Surface lift handle, single-point latch (supervised employee)
Surface lift handle, multi-point latch
7.5.3The latch and handle shall be selected for the service environment: recessed handles and recessed latches for corridor and athletic rooms to reduce snag and vandalism, and surface lift handles for supervised employee use.
7.5.4Multi-point (three-point) latching shall be specified for unsupervised, abuse-prone corridor and athletic lockers to resist prying.
7.6 Locking Method
NOTE Built-in combination locks suit schools and shared institutional use; padlock hasps let users supply their own locks; key locks suit assigned employee lockers; electronic locks suit day-use and shared lockers where users set their own code per use. (7.6.1)
NOTE Where electronic locks are hard-wired or networked, power and data rough-in is coordinated with the electrical trade before fabrication. (7.6.2)
Recessed padlock hasp (user-supplied padlock)
Built-in combination lock (single-combination, assigned)
Built-in resettable/multi-user combination lock (shared/day-use)
Built-in key lock (cam/cylinder, keyed, master-keyed)
Electronic keypad/RFID lock (programmable, day-use or assigned)
Provision for Owner-furnished lock (hasp/cutout only)
○ Keyed alike within control group, master-keyed (key locks)
○ Combination set list provided to Owner (combination locks)
○ Owner-programmed at commissioning (electronic locks)
○ Not applicable (user-supplied padlock)
7.6.3The locking method shall be selected for the Owner's access-control needs, the user population, and the willingness to manage keys, combinations, or batteries.
7.6.4Electronic locks shall be specified with a clearly defined power source (battery or hard-wired).
7.6.5Electronic locks shall be specified with a documented mechanical or master override for lockout recovery.
7.6.6Where electronic locks are hard-wired or networked, power and data rough-in shall be coordinated with the electrical trade before fabrication.
7.6.7Where electronic locks are battery-powered, the closeout submittal shall state the battery type and the expected service interval.
8 Accessories and Trim
NOTE Trim and accessories finish a locker installation, close gaps to walls and soffits, keep dust and debris off and out of the lockers, and identify openings. (8.1)
NOTE They are selected for the installation condition and the housekeeping environment. (8.2)
8.3 Sloped Tops
NOTE Omitting sloped tops in a dusty or unsupervised environment is a common and avoidable maintenance failure. (8.3.1)
○ Continuous sloped tops (prevents storage/dust accumulation atop lockers)
○ Flat tops (storage shelf above, low-dust environment)
8.3.2Continuous sloped tops, typically 16-gauge with an approximately 18-degree pitch, shall be specified for corridor, athletic, and public installations to prevent the locker tops from becoming a dust shelf and an informal storage surface.
8.3.3Sloped-top end closures and splice covers shall be furnished to finish exposed ends and joints.
8.4 Base
NOTE A Z-base (channel base) raises the lockers off the floor and creates a recessed toe space, improving appearance and simplifying floor cleaning; closed bases conceal legs for a finished look in public areas. (8.4.1)
Closed (front and end) base over legs (conceals legs, finished appearance)
Z-base / channel base, 4 in (raises lockers, creates toe space)
Z-base / channel base, 6 in
Legs exposed (utility/back-of-house)
No base — lockers set directly on finished floor
8.4.2The base condition shall be coordinated with the finished flooring and base trades.
8.5 End Panels, Filler Panels, and Recess Trim
○ Finished end panels at all exposed locker ends
○ No finished ends (ends concealed by walls)
○ Provide filler panels to close gaps to walls, columns, and obstructions
○ Not required (lockers fit module exactly)
○ Provide recess trim where lockers are recessed into wall/soffit
○ Not required (lockers not recessed)
8.5.1Finished end panels shall close exposed locker ends.
8.5.2Filler panels shall close the gaps between lockers and walls, columns, or obstructions.
8.5.3Recess trim shall bridge the gap to the wall and soffit where lockers are recessed.
8.5.4Filler and trim quantities shall be confirmed against field dimensions before fabrication, because gap and obstruction conditions are not always apparent until field measurement.
8.6 Number Plates
NOTE An arbitrary numbering sequence forces the Owner to renumber after installation, so the sequence is set from the Owner's locker-assignment scheme. (8.6.1)
○ Provide number plates, sequence per Owner schedule
○ Provide number plates, sequential by bank
○ Not required
8.6.2Number plates shall be riveted to each door at a consistent location.
8.6.3The numbering sequence shall be coordinated with the Owner's locker-assignment scheme.
8.7 Interior Equipment and Benches
☐ Coat hooks / single-prong wall hooks
☐ Double-prong ceiling hooks
☐ Coat rod (single-tier garment lockers)
☐ Top shelf
☐ Footwear shelf / bottom shelf
○ Provide benches (hardwood top on pedestals), lengths per drawings
○ Not required
8.7.1Where benches are provided, hardwood bench tops on metal pedestals shall be the standard.
8.7.3Where accessibility requires it, at least one bench complying with the accessible-bench provisions of the accessibility standard shall be provided in each locker room (see Accessibility below).
9 Accessibility
9.1 Coverage
NOTE The 2010 ADA Standards (Sections 225 and 811) and ICC A117.1 require that at least 5 percent of lockers of each type, but no fewer than one of each type, comply. "Each type" includes each functional class of locker (for example, full-height garment lockers and box lockers are different types and each requires its accessible share). (9.1.1)
○ 5 percent of each type, minimum one of each type (per ADA 811 / A117.1)
○ Greater quantity as indicated on the drawings
9.1.2Where lockers are provided, accessible lockers shall be provided in accordance with the adopted accessibility standard.
9.1.4The Architect shall confirm the count and configuration of accessible lockers from the accessibility compliance path.
9.2 Reach Ranges and Operable Parts
NOTE The defining requirement for an accessible locker is that its usable storage and every operable part fall within the reach range. (9.2.1)
NOTE Accessible lockers are normally located in a single tier or in the lower tier of a multi-tier bank so that the opening and the lock are reachable from a seated position. (9.2.2)
9.2.3A conventional small combination dial or a key cam lock that must be pinched and twisted does not meet the operable-parts criteria.
1548
15364448
Default: 44 in AFF
Built-in combination lock with large, easy-grip dial/buttons
Electronic keypad/RFID lock (no grasping or twisting)
Recessed padlock hasp (only where padlock meets operable-parts criteria)
9.2.4The usable storage in an accessible locker shall be within an unobstructed forward or side reach range of 15 in. minimum to 48 in. maximum above the finished floor.
9.2.5Every operable part of an accessible locker — handle, lock, keypad, and latch — shall be within the 15 in. to 48 in. reach range above the finished floor.
9.2.6Every operable part of an accessible locker shall be operable with one hand without tight grasping, pinching, or twisting of the wrist, and with no more than 5 lbf of force.
9.2.7Accessible lockers shall use a lock operable with a closed fist or one easy motion.
9.2.8A clear floor space and an accessible route shall be provided at each accessible locker.
9.2.9The clear floor space at each accessible locker shall be verified against the locker plan.
9.3 Accessible Benches
9.3.1Where benches are required in a locker room, at least one bench shall comply with the accessible-bench provisions (seat height, depth, back support, and clear floor space) of the accessibility standard.
9.3.2The accessible bench and its clear floor space shall be coordinated with the locker layout so the clearance is not blocked by a locker bank.
10 Fabrication
10.1Lockers shall be fabricated to the dimensions and configuration shown on the approved shop drawings.
10.2Welded lockers shall be factory-welded into rigid units with welds ground smooth at exposed surfaces before finishing.
10.3KD lockers shall be fabricated with formed, flanged components that assemble into square, rigid banks with mechanical fasteners.
10.4Doors shall be formed with a continuous channel or box section at the lock edge.
10.5Doors shall be hung to operate freely without binding, with the latch engaging the strike fully.
10.6Louvers, perforations, and ventilation openings shall be formed without sharp or burred edges.
10.7All components shall be cleaned, phosphatized, and powder-coated after forming and welding so that cut and formed edges are coated.
10.8All exposed welds shall be ground smooth before finishing.
10.9All sheared and formed edges shall be free of burrs and sharp edges.
11 Installation
11.1 Coordination and Blocking
NOTE Blocking is furnished and installed under the wall trades; anchoring lockers or benches to gypsum board without blocking is a primary cause of failure. (11.1.1)
○ Yes — blocking verified at all wall anchorage points before installation
○ Not applicable — no wall-anchored components
11.1.2Lockers shall be installed after the wall and floor finishes are complete and the building is enclosed and conditioned.
11.1.3The Contractor shall verify before installation that solid in-wall blocking has been provided where lockers, trim, or benches anchor to walls.
11.1.4The locker Contractor shall confirm the presence and location of blocking against the shop drawings and shall notify the Architect of any missing or mislocated blocking before proceeding.
11.1.5Anchoring lockers or benches to gypsum board without blocking shall not be permitted.
11.2 Anchorage
Floor-anchored and wall-anchored (back to wall)
Floor-anchored and top-anchored to wall (tall single-row banks)
Back-to-back freestanding, floor-anchored and braced
Recessed into wall opening, anchored to surrounding structure
11.2.1Lockers shall be set level and plumb, shimmed as required, and anchored to the building structure.
11.2.2Banks shall be bolted together into continuous runs and anchored to the floor and, where backs are accessible, to the wall.
11.2.3Anchorage shall use fasteners appropriate to the substrate — expansion or wedge anchors into concrete, anchors into masonry, and through-bolts or lag screws into in-wall blocking within stud walls.
11.2.4Tall lockers shall be anchored at the top to the wall or, where freestanding, braced back-to-back, so they cannot tip.
11.3 Seismic Restraint
○ Yes — seismic anchorage per ASCE/SEI 7 and sealed calculations
○ No — not required by the seismic design category
NOTE Seismic restraint is determined by the project's seismic design category and the locker height and weight. (11.3.1)
11.3.2Where the seismic design category requires anchorage of nonstructural components, lockers (particularly banks 60 in. or taller) shall be anchored vertically and laterally to resist the seismic forces determined per ASCE/SEI 7, in accordance with the sealed anchorage calculations and details submitted under Submittals.
11.3.3The Architect and Structural Engineer shall confirm the seismic-restraint requirement.
11.3.4Anchorage relying solely on sheet-metal screws into unbraced studs shall not be accepted as satisfying a seismic anchorage requirement.
11.4 Adjustment and Cleaning
NOTE Field touch-up does not reproduce the baked finish, so damaged components are replaced rather than field-repaired. (11.4.1)
11.4.2After installation the Contractor shall adjust every door so it operates freely, latches fully, and the lock engages.
11.4.3After installation the Contractor shall verify that accessible lockers' operable parts are within the reach range and operable as specified.
11.4.4After installation the Contractor shall install all trim, number plates, and accessories and shall clean all surfaces.
11.4.5Protective coverings shall remain in place until adjustment and cleaning are complete.
11.4.6Doors that bind, latches that do not engage, and finish damage shall be corrected.
11.4.7Deep scratches and corroded components shall be replaced rather than field-repaired.
12 Warranty
NOTE Welded heavy-duty locker programs commonly carry substantially longer warranties than standard-duty KD lockers. (12.1)
1 year from substantial completion — standard
5 years from substantial completion
Lifetime limited warranty against defects (welded heavy-duty programs)
Manufacturer's standard lock warranty (mechanical locks)
Extended electronic-lock warranty including controller and keypad
1 year from substantial completion
2 years from substantial completion
12.2The manufacturer shall warrant the lockers against defects in materials and workmanship — including finish adhesion, door and latch operation, and structural integrity of the body and frame — for the specified period.
12.3Where the project uses welded construction, the longer warranty offered by the welded program should be obtained and documented.
12.4The warranty shall not cover abuse beyond the rated service condition, improper cleaning chemicals, or modifications made without the manufacturer's authorization.
12.5The Contractor shall warrant the installation — including level and plumb setting, anchorage and seismic restraint, door alignment, and compliance of accessible lockers with the reach-range and operable-parts requirements — for the specified period.
12.6Deficiencies attributable to installation workmanship shall be corrected by the Contractor at no cost to the Owner.
