A standard radiused tubular mortice latch for domestic situations, ideally suited for handles that are already sprung. Many housebuilders such as Wimpey Homes have these rounded type latches fitted by the door manufacturer, and therefore can be difficult to obtain on the high street. Standard dimensions mean an easy retro-fit replacement.
