Yale PBS1 BS3621: 2007 High Security Nightlatch

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.

The Yale PBS1 High Security Nightlatch lock has been approved to BS 3621:2007, BS EN 12209:2003 and BS EN 1303:2005 the highest level of certification currently available making them one of the best available from the original Yale lock inventor.

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.

This 60mm backset nightlatch is operated by key from outside and via lever turn on the inside, with an internal cylinder with which to deadlock the door and prevent the lever being manipulated from outside EG via the letterbox etc.

Supplied with a high security TS007 approved rim cylinder that includes reinforced protective escutcheon plate. This cylinder is supplied with 2 genuine keys

Ideal for use on wooden front doors where the highest level of security is required.
