2. – 3. Height Adjustment or Compression Adjustment

Height adjustment can either be No 2 or No3 depending on the make and model of the hinge.

Remove the plastic plug No1 and insert an Allen Key into the hole, turn the Allen Key until the door starts to pull back towards the hinge side of the frame. Note how many turns you have completed and adjust the middle hinge (if fitted) by the same amount until the door is level with the frame. Keep checking after every adjustment to see if the door is closing and locking correctly.

If the door has been fully adjusted and still does not close or lock correctly there are a couple of things that you may want to try. The first is to adjust the bottom hinge away from the door. This will lift the door on the lock side, but be aware that sending the door out at he bottom will also narrow the gap between the lock and the bottom keepers and any over adjustment may make the lock or door hit the frame or keepers. The second thing you can try is to move the keepers down until they are in line with the Latch, locking Bolts, Hooks and or rollers.

Butt Hinges:
