DOOR BLØK
LOCK BLOK

Works on all classroom doors Regardless of the hardware used on the doors at your site--knobs, handles, or panic bars--LOCK BLØK will work on every single one of them.

Built to LastThe 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.

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.

LOCK BLOK in open position

Open Position 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: Students are able to easily enter or exit the classroom without disturbing others.

Closed Position By moving the slide away from the edge of the door, the door will close completely and engage the latch.

Lock Blok Advantage 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.
