The Yale British Standard PBS BS3621 Nightlatch Polished Chrome is one of the few insurance-rated nightlatches on the market. In addition to automatically deadlocking when the door is in the closed, the inside handle can be locked by a turn of the key. Entry can always be gained by key, from outside, whether the inside handle is locked or unlocked.

Other Variations

The night latch is also available in a brasslux/brass finish and with a standard 90mm case size – some of these variations can be found in the related products.

Latch Size

The nightlatch is to suit specific size door stiles; the nightlatch has a body width of 69mm and height of 90mm. A security cylinder pull is provided with each size and must be fitted to the door. The pull is designed to foil attempts to pick or drill the cylinder and is an integral part of the BS3621 approval. Removing it during installation invalidates the insurance rating of the lock.
