Deadlocking standard night latch with a dark metallic grey case and a polished brass cylinder. An additional feature is that the inside handle can be deadlocked from the outside when leaving the premises. Supplied with 2 keys. This lock has a 60mm backset and is suitable for doors with no restriction on width. It offers standard security. The inside handle can be deadlocked by a reverse turn of the key in the outside cylinder after closing the door. Operation is by key from the outside and a lever handle on the inside. The snib function enables the latch to be held back. The latch can be deadlocked by the snib button internally, making the lock inoperable by key or handle. Suitable for both left and right handed, inward opening doors up to 57mm thick. For outward opening doors, please call the Yale helpline for advice. This brass effect night latch is ideal for securing both left and right handed, inward opening doors. Recommended for use in conjunction with another lock, such as a deadlock or Euro cylinder.
