Adjustable Catches for Quiet Door Closing
Roller catches hold an internal door closed using a spring-loaded roller that engages with a keep. They suit doors opened by a fixed knob, pull handle or push action where a conventional lever latch is unnecessary.
Accurate alignment matters more than force. Set the roller projection so the door closes positively without needing a hard push, then position the keep around the roller centre. Compare other closing options in the locks and latches collection.
A roller catch will not correct a door that has dropped or twisted. Tighten or replace worn door hinges first. Finish the opening with suitable pull handles or fixed door furniture that allow the door to be drawn from the keep.
