Multipoint Gearbox - Lift Lever or Split Spindle

Product Information

Introducing the Surelock multipoint door lock gearboxes, designed with a unique square shape and no corner cut-outs. These gearboxes measure 220mm in overall length, with a width determined by the backset plus an additional 18mm.

Available backsets include 35mm and 45mm options.

The Surelock gearboxes feature a 24mm high latch, distinguished by two screws, and a 30mm high deadbolt, with a spacing of 61mm between them. Uniquely, these gearboxes are secured to the faceplate with four screws. The measurements between the screw holes are as follows: 37mm from the first to the second, 85mm from the second to the third, and 43mm from the third to the fourth.

When measuring the backset, remember to account for an additional 2-3mm for the faceplate. Therefore, a 35mm backset gearbox will measure approximately 32mm when not attached to the strip.
