FAQ

How does the mechanism work?

The flat piece (PrusaLock) has small protrusions around the opening. Those notches are designed to enter the hole in the strike plate your door locks/closes into. PrusaLock fits in the gap between the door and the strike plate. When you close the door, the bolt should continue to go through the hole in the PrusaLock into the recess in the strike plate. Once the door is closed, you put the triangular piece (Block) to lock the block onto the PrusaLock as close to the door as possible. The Block should rest across the frame and door.

The result of this is even if someone were to unlock the door and open it from the other side if they pushed against the door, it would hit up against the block, preventing an individual from opening the door. Because the flat piece is notched into the recess and is wedged between the door and frame, it cannot be removed without opening the door. The combination of those two things locks the door even if someone can turn the doorknob.

The gap between my door and door frame is too thin, what should I do?

PrusaLock is 3mm thick. If a nickel (~2mm) fits in the door gap, then PrusaLockThin should fit.
