When replacing any locks, it is better to fit the highest security option you can afford.  To meet the police preferred and insurance approved specification, at least one of the locks on your front door must meet the BS 3621 kite marked standard.

Nightlatches that conform to the BS 3621 standard are particularly recommended for front doors as they offer the convenience of automatic locking when the door is closed.

 For greater security, choose a nightlatch from the Yale X-Tech range.

As the No.1 brand in nightlatches, Yale have undertaken an exhaustive programme of consumer research to find out what you want and expect from the next generation of locks. The result is the X-Tech range.

The X7, X8 and X9 nightlatches come in several sizes, a variety of finishes and with excellent features to increase the security of your home.
