The housing--below left--is made of durable, impact-resistant ABS plastic.
The slide--below right--is a half-inch thick piece of 40 duromenter neoprene that has been precision cut with a computer-controlled waterjet system.
Note: For step-by-step installation directions, download the instruction sheet.
There are two adhesive strips on the back side of the housing. The housing--attached to the side of the classroom door that comes in contact with the latch--traps the rubber slide but allows it to move side-to-side.
The slide prevents the door from being able to close completely.
As you can see below, leaving the slide in this position will prevent the door from closing the way it normally would. This prevents the latch from engaging.
Benefit: The classroom door can remain locked all day while still allowing students to easily enter the classroom.
No knocking on the door. No need for assistance. Just a silent entry.
By moving the slide away from the edge of the door, the door will close completely and engage the latch.
One big advantage of LOCK BLOK is that it adheres to the door. Once attached with the adhesive strips, it's not going anywhere.
DOOR BLOKs, on the other hand, merely hook around the knobs or handles of the door. Consequently, a DOOR BLOK can sometimes "walk away" from the classroom. This is especially true at the secondary level where students are a bit more inclined to mess with things they're not supposed to mess with.
