Tripact New Style Genuine Multipoint Gearbox – Lift Lever

GU genuine gearbox to suit new style GU Tripact 70mm PZ locks only, not compatible with old style versions.

New style GU gearboxes are available in 40mm and 50mm backset options and work via lift lever operation with an unusual smaller 7mm square spindle follower.

New style GU Tripact locks can be differentiated from their old style equivalents by the shape at the bottom of the gearbox. Old style locks have a rectanguler case with rounded corners, whereas new versions feature square cut out on the bottom back corner below the euro cylinder piercing. The two gearboxes are not compatible, so a new style gearbox will not fit on an old style multipoint lock.

GU multipoint lock gearboxes feature a latch and deadbolt and measure 213mm high with a width of 16mm plus the backset size. The latch is 32mm high, the deadbolt measures 33mm high and there is 54mm from the bottom of the latch to the top of the deadbolt.

GU gearboxes are fixed to their faceplates with 3 screws. The distance from the top to the middle screw is 110mm, while the middle screw to the bottom screw is 95mm.

Always allow 2mm when measuring your backset and the faceplate is still attached to the gearbox.

Will fit new style GU locks only, not compatible with old style versions.
