These GU locks are used on french doors and feature serrations to allow the attachment of top and bottom shootbolts.
- Overall length – 1830mm
- GU locks are now manufactured with a new style centre case
- The main difference between old and new style is the distance between the latch and the deadbolt, this will sometimes cause problems with strike plates
- The other major difference in the height of the lockcase, although this shouldn’t cause any real problems when retro fitting
