C600 Genuine Multipoint Gearbox – Key Wind

C600 gearboxes measure 213mm x backset + 18mm. They feature a 30mm x 10mm latch, a 30mm high bolt and 57.5mm between the latch and deadbolt. Gearboxes feature a distinctive elongated piercing that measures between 136mm and 173mm from the centre of the euro cut out, to accept bolts for handles.

Roto C600 multipoint door lock gearboxes feature a “whisper latch” as standard fitment. This latch has a central plastic component to ensure that the door closes quietly. It’s worth noting that Roto did supply these locks with other types of latch, which although rare, may not feature the plastic insert.

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.

We stock a range of associated products for Roto C600 gearboxes, including multipoint door locks, keeps, spindles, handles and accessories.
