## Mesh Opening and Gauge {toc}
−### The mesh opening shall be as scheduled below; a smaller opening increases security and reduces reach-through but also reduces visibility and airflow. {note}

# Enclosure Configuration {toc}
−## The number of sides and the top condition shall be selected to match the security requirement; an open-top enclosure can be defeated by climbing over and is unacceptable for security-critical uses. {note}
