LockMaster 2 Hooks, 2 Anti-Lift, 4 Rollers UPVC Multipoint Locks

If you're looking to replace your multipoint lock with something robust and well thought out, this may be well worth your consideration.  

Offering two anti-lift hooks, a centre latch and deadbolt, with four rollers to minimise weak spots, this lock achieves a very strong and rigid hold into the frame when locked in place.

The hooks at the top and bottom are aided by cylindrical bolts or 'pins' which prevent any lift-attacks whereby an intruder may attempt to pry the door up off the hinges in order to mitigate the security of the lock itself.  Then, the centre deadbolt and the supporting four roller cams mean that the entire door is kept rigid and firmly secured, reducing the possibility of flex or any other weak spots from being exploited in an attempt to gain unauthorised access.

Set on a 16mm rail as standard, these offer a typical 92/35 setup.  This relates to the 92mm PZ measurement which is the distance between the centre of the keyway on the euro profile and the centre of the follower for your square spindle; and then the 35 relates to the backset measurement, whereby 35mm is extremely common on uPVC doors.
