ERA British Standard Nightlatch — 60mm Backset, Passage Function, Brass

The ERA British Standard Nightlatch Passage Function (DF1930BP) is a high-security door lock with a classic and robust design. Available in a 60mm backset, it is an ideal product to replace most existing front door locks. The passage function allows the latch to be held in the withdrawn position for free passage — ideal for high-traffic doorways.

The ergonomic internal locking handle can be deadlocked by an anti-clockwise turn of the key from the inside, offering additional security against forced entry. The main bolt is automatically deadlocked into the striker when the door is closed, preventing it from being retracted by a credit card. Designed with a 20mm bolt throw for even greater security and strength.

Face-fitted and non-handed, it suits both left and right-hand inward opening timber doors. The striker features a 3-hole fixing for added strength. The lock conforms to BS 3621:2007 (BS EN 12209) and meets the requirements of insurance companies and the Police. Supplied with 3 cut keys; can be keyed to pass or master keyed. All finishes meet BS EN 1670 Grade 3 (96 hours) corrosion resistance.
