The door is lockable from inside the classroom without requiring the door to be opened. This prevents the risk of exposure to an intruder.

Egress from the classroom is accomplished without using a key, a tool, special knowledge, or effort. No need to worry about lost keys or special tools, and extensive training is not required.

Exiting the classroom is accomplished with one motion by pulling the red cable, which unlocks the bolt from the latch.

The classroom door is unlockable from outside the classroom.

Door operating hardware is operable without tight grasping or twisting of the wrist. This enables people with weak hands to open the door.

The locking parts inside the classroom are mounted between 34 and 48 inches above the floor. This allows people of short stature or in wheelchairs to operate the lock.

The bottom 10 inches of the "push" side of the door surface are smooth. This prevents wheelchairs from getting caught and blocking the egress path.

The hole drilled through the door to install the locking cable path does not exceed 3/4".

Locking the door is quiet to minimize noise and help prevent drawing attention from an intruder.

The screws used to attach the bolt receiving latch mounted to the door frame are 2-½” in length to penetrate studs to reinforce the strength of the lock.

The lock is functional without electricity, batteries, keys, or unique tools and cannot be operated remotely.

Nothing is mounted, attached, or drilled into the floor that may cause a person to trip or a wheelchair to become stuck in the doorway.
