Dozens of “alternative” products are being marketed for use in homes, apartments, dorm rooms, offices, churches, and schools. Just to reiterate…egress doors in schools and most other occupancies must unlatch with one releasing operation (or two, in some cases). The hardware must allow egress with no key, tool, special knowledge or effort, and with no tight grasping, pinching, or twisting of the wrist. The releasing hardware must be mounted between 34 and 48 inches above the floor (34-44 inches in California). And the 2018 model codes require classroom doors to be able to be unlocked from the outside with a key, credential, or other approved means.
