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 ERA 193 double-locking nightlatches automatically deadlock on closing, due to the snib, preventing the main latch bolt being ‘slipped’ open from outside. Ideally suited for solid and glazed panelled timber doors between 35mm and 60mm thick. The modern styling and solid contruction have helped make this a popular nightlatch. A 5 pin rim cylinder and 3 keys come supplied as well as all fixings.

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 also 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 outside and lever operated inside with an internal cylinder within the lever handle. The internal handle can be deadlocked by an anti-clockwise turn of the key from the inside securing the lock against forced entry.
