DoorJamm is an easier to carry access control device for preventing doors and gates from closing behind you. It’s simple, flat form is constructed from stretchable, abrasion resistant material that allows it to be stretched onto the door knob on both sides of the door, blocking the latch.
A stack of DoorJamms takes up less space in a pocket or bag than a single wedge and is easier and more effective than an improvised item like tape or a business card. It stays in place until you retrieve it and is reusable.
DoorJamms are available for individual sales, department sales, and wholesale to uniform and tactical gear shops. Check out DoorJamm.com.
