Door Latch Stop

thingiverse

As a teacher we need to leave the doors locked (or able to be locked quickly) in the event of a lockdown. These blocks are designed to be placed into the door jamb opening to keep the door from engaging and to being able to lock. This is quickly removable in the event that the door needs to be locked without the need to get keys and mechanically lock the door. The second is used on doors with a crash bar (push bar), to hold the door in the open position without the need to use keys to physically lock the door in the event of an emergency. Version 2 has additional angles to "squeeze" a bit more and hold into place harder.
