Instructions On How To Fit a Suffolk Thumb Latch To Your Door

how to fit thumb latch to door DIY Fitting instructions

  1. The traditional height for fitting the thumb latch is about 1300mm from floor.
  2. 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.
  3. Fix the handle onto the door using one screw only in top & bottom, fix so that the thumb bar going through door is level.
  4. 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).
  5. 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. 
  6. 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.
  7. If you push down on thumb latch or lift hooked end of thumb bar the latch bar should rise up out of keep.
  8. If all parts work and door opens & closes put the remaining screws into the handle.
  9. 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.how to fit a traditional thumb latch DIY Instructions
