40mm Non Deadlocking Nightlatch

Product Information

Nightlatches are a common locking product found mainly on residential front doors. They ordinarily feature a single sprung latch locking point which engages automatically when the door is shut, securing the property.

These Yale 84 40mm Non-Deadlocking Nightlatches are a common sight throughout the UK and have been on the market for many years. This small backset version is specifically designed for doors with narrow stiles that cannot accept the larger 60mm backset size of standard nightlatches.

Part of the Yale modern nightlatch range, this nightlatch features a more contemporary styling and appointments, and the neutral styling is suited to most homes. This recognizable range offers all the quality associated with any Yale nightlatch.

These non-deadlocking units come with a Yale 5 pin rim cylinder and 2 keys, or can be supplied in a range of finishes. A case-only version is available if no cylinder is required (grey finish only).

This nightlatch features a means of mechanical holdback which allows the sprung latch bolt to be physically retained within the body of the nightlatch. When this feature is activated, the latch will not engage when the door closes, therefore the door will not be secured. It is important to consider if this is a feature that is desirable for the application in question, as in some circumstances the possibility of the door not being secured may cause issues. Also, some mechanical holdback devices allow the latch to be secured in the locked position, preventing access even when a key is used from outside, deadlocking the door. It should also be considered if this is suitable for the application.

Key operated from the outside and a thumb turn operation from the inside.
