Defensive Door Wedges Mk II

Its doesn't matter if you want to keep a door closed from the inside, or the outside. These ratcheting door wedges lock securely. Clear a room, then use a pair of wedges to maintain its security. They can be interlocked to ratchet and maintain an incredible grip.
If you are in a room and want to keep people out, the wedges can help with that too.
You could drill them to add a cord for easy removal or carry in bulk.

Theres a whole lot of uses and at this price, theres no reason not to carry them with you as a useful EDC.

Mk II Wedges are slightly larger as requested from feedback.
