Safe-Latch by Safe-Latch, LLC is a product that helps schools enforce their locked door policies, making classrooms safer, for under $30 a classroom. Safe-Latch was designed to slide between the door and door frame, allowing interior doors to be locked, at all times. In an emergency, Safe-Latch can quickly be pulled from the door, locking it, without the use of a key. Installation is minimal and does not require a change in door hardware. Safe-Latch is a school-wide solution for teachers, administrators, substitutes and students, and requires no training to use.
