How To Fit A Suffolk Thumb Latch
How To Fit a Suffolk Latch
- The traditional height for fitting the thumb latch is about 1300mm from floor.
- Drill a row vertically of 6mm holes one above the other, then with the use of a chisel, complete the holes to make a narrow slot for the thumb bar to go through the door, about 90mm back from the shutting edge.
- Fix the handle onto the door using one screw only in top & bottom, fix so that the thumb bar going through door is level.
- Position the latch bar on other side so that the lower edge of bar rests on top of thumb bar & hangs over the edge of door by about 30mm. Put a screw in the central hole leaving loose enough for bar to move up & drop down freely. (Check that when pressing down with thumb on handle side that thumb bar rises to lift latch bar).
- Mark lines across face of frame to show position of frame keep. When bar is horizontal drill a guide hole into frame (3mm dia) just under this line to a depth of 25mm, about 15mm from the edge of the door.
- With the door closed and the latch bar going across the frame, the keep should be fixed into position on the door frame. Note - you may need to cut out the frame architrave in some applications. Some keeps are screwed in to place others have a simple spike which is tapped into place. Do not screw or tap in to tightly - stop before it pinches latch bar.
- If you push down on thumb latch or lift hooked end of thumb bar the latch bar should rise up out of keep.
- If all parts work and door opens & closes put the remaining screws into the handle.
- NOTE - It may be necessary to fit a 'lock block' - a piece of wood to the door to allow the correct fitting as shown here.
- Stand back & admire your hard work!
