Yale Locks - 89 Deadlock Nightlatch 60mm Backset DMG Finish Box

Description from the shop

The Yale 89 is a deadlocking nightlatch designed for front doors. It operates via key from the outside and lever handle from the inside, with the latch automatically deadlocking when the door closes. A snib function allows the latch to be held back, and the inside handle can be deadlocked by reverse key turn for additional security, preventing internal opening. This variant features a Dark Metallic Grey case finish with a Polished Brass cylinder (1109). The 60mm backset is the measurement from the door edge to the keyhole centre. The lock carries a 2-year guarantee and a high security rating.
