Ingersoll SC71 Deadbolt Rim Nightlatch (Inward opening doors)

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 Ingersoll SC71 type ‘Classic’ nightlatches contain a 10 lever key mechanism, making them incredibly secure. With it’s reinforced, hacksaw resistant deadbolt, these nightlatches automatically lock on closing the door and can be double locked. They have proved extremely popular over many years with their design remaining unchanged, and have a reuptation for being a secure, reliable lock type.

Designed for inward opening doors with a thickness of between 38mm – 58mm, these locks use a specially designed external cylinder, and a unique pull type handle on the inside case which is more difficult to manipulate through a letterbox or window.

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.
