The ERA Double Locking Night Latch 60mm backset, designed to replace most existing front door locks. The product is ideally suited for solid and glass panelled wooden doors, as it has been designed with an ergonomic internal locking handle offering added security against forced entry. The main lock bolt is “automatically” deadlocked when the door is closed, preventing the main bolt being retracted by a credit card. The inside handle can be deadlocked by an anti-clockwise turn of the key from the inside so securing the lock against forced entry. The bolt can be held in the withdrawn position (only) with the use of the snib feature. The bolt cannot be reversed. Sizes: Backset: 60mm
