These latches are one of the most evocative period pieces available to you if you are creating an authentic feel and atmosphere with your restoration project. The thumb piece passes through the door and raises the latch bar off the keep. To restrict the latch bar movement a staple pin and a screw-on staple pin are provided (discard unused pin or find another use around the home). Comes with an extra long thumb bar for use on doors with a maximum thickness of 75mm. Sold as a set and supplied with necessary fixing screws. If you require locking your toilet or bathroom door the locking staple pin or the locking screw-on staple pin is the answer. They have a leather thong with a pin to stop the movement of the latch bar.
