A simple snib button on the inside allows the latch to be held back or deadlocked internally for everyday convenience. The ERA Replacement Nightlatch is available in either a 40mm or 60mm backset (measured from the edge of the door to centre of keyhole/ handle). All screws are included. 1 Year mechanical guarantee.
