Anti-lock snapping cylinders as standard

<< Back to Latest News, Security

Ensure you have anti-snap lock on your replacement doors

Lock snapping is where the lock cylinder is literally snapped in two by applying force to the cylinder, usually with a screwdriver.

Thieves have devised methods of snapping these types of cylinders locks in a matter of seconds and still be able to operate the lock to open the door.

A recent report from the BBC explains:

The threat of having your home broken into by thieves who can ‘lock snap’ can be considerably reduced simply by upgrading the cylinder to one that is especially designed to prevent this method of entry. 

Capital Windows supply anti-lock snapping cylinders as standard

At Capital Windows we ensure that all replacement doors are supplied with ‘break secure’, or ‘anti-snap cylinders’ as standard. These are specifically designed to combat lock-snapping and supplied as standard as a demonstration of our commitment to deliver only the best.

These anti-snap locks have been designed to snap, however, they snap in a predetermined position leaving intact a portion of the cylinder that will still provide security and still require key operation to open, thus preventing the easy manipulating of the locking system – voila!

Replacement lock cylinders should meet all parts of the exacting British Standard Kitemark (BS EN 1303:2005) accreditation scheme.

If you have a Secured by Design door fitted after 2010 you can be confident that it will have a “Break Secure” lock. Please note this applies only to Secured by Design doors and not all doors.
