GU 2 Hook, 2 Roller UPVC Door Lock

This multipoint lock by GU offers a little more than just hookbolts, as it also incorporates two roller cams along the locking strip between the centre case and the top and bottom hooks. 

While roller cams alone do not offer the best level of security, when used in conjunction with hookbolts, what you get is a far superior grip into the frameside than the hooks alone can achieve. 

The roller cams between the two hookbolts and the centre latch & deadlock allow the door to be secured all the way along the door, rather than just the top, bottom and centre.  This minimises any possible flex on the door and makes sure the door always locks snugly across the full height of the door.

Avalable with a 35mm backset, and situated on a 16mm rail, this lock is designed mainly for the plastic / uPVC door market.  And with its 92mm PZ centres, this is a very 'universal' type fit and can replace a large amount of existing installed multipoint locks.
