Lock & Block Schoolroom Security Lockdown Devices
Allow locked doors to be opened and closed by students all through the day without the door locking. When lockdown is needed, one simple movement of the device securely locks the door. Inexpensive, easy to install and easy for teacher and students to use. The locked door can then still be opened from inside the room by turning the door knob and from out in the hall with a pass key.
