Yale 84 Standard Nightlatch 40mm Backset DMG Finish

The Yale 84DMGPB is a high-security nightlatch designed for doors that require reliable external key access and interior lever operation. It features a dark metallic grey hardened case with a polished brass cylinder, and is suitable for narrow or restricted spaces such as doors with a 40mm backset. The lock operates with a key from the outside and a lever from the inside, and the latch automatically deadlocks when the door is closed. A snib function allows the latch to be held back for convenience. Supplied with the B-1109 key cylinder, this model is part of the 84 series and is covered by a 2-year guarantee with a standard security rating.”
