Roto H650 passive gearboxes are dimensionally the same as the H600 series but feature internal upgrades. They are available in a 35mm backset with single spindle operation.

The H650 gearbox measures 212mm high by the backset + 15mm. The latch is 29mm high, the deadbolt is 30mm high and there is 58mm between the bottom of the latch and the top of the deadbolt. Gearboxes are fitted to faceplates with three screws. The top to middle screw measures 70mm, whereas the middle to bottom screw measures 125mm.

European markets feature locks with 25mm up to 80mm backsets, but locks with 35mm and 45mm are sold in the UK. When measuring the backset, allow 2-3mm for the faceplate, so a 35mm backset gearbox will measure 32mm when not fixed to the strip.
