Latch guide in mounting plate and built-in electric strike

Latch guide is used when the electric strike is mounted in the central part of the door frame, it is most commonly used in non-rebated doors.  

Solution without and with latch guide

Latch guide ensures smooth operation of the latch in a knob lock, while protecting the door frame against damage. It also prevents the door lock bolt from falling into the space between the electric strike and the door frame, which can cause the door to jam. The latch guide integrated with the electric strike, as well as the guide used in the hook plate, is ideal for non-rebated doors and narrow door frames.
