Yale Doormaster™ Universal lock uses the latest patented technology from Yale to ensure security and simplicity of installation. It is designed to replace 100% of PVCu door locks with a 35mm or 45mm backset and a 16mm faceplate. The revolutionary new range means that if a multi-point lock is broken, the lock - rather than the whole door - can be replaced.

The one-piece mushroom rollers ensure smooth operation and help prevent separation. These easily adjustable rollers create a weather-tight seal to protect the interior of homes against the elements and help to keep warmth in. The centre hook protects against attack, and helps in preventing separation.

Doormaster™ is supplied with a fully assembled one-piece keep, which includes the patented Uni-packer™ system for fast, easy and reliable installation. Fixing tabs make fitting easy and more secure.

Doormaster™ locks are suitable for most PVCu, Composite or Timber doors. They are available for doors with a single hook or bolt in the centre of the door, and also for locks with additional hooks or bolts at the top and bottom of the door.

10 year guarantee.
