Ingenious Genuine Multipoint Gearbox – Lift Lever

Ingenious gearboxes have a distinctive double spindle arrangement with centres at 62mm and 92mm. Both followers are unsprung so we’d recommend the use of sprung door furniture. The top corner of the gearbox is also cut out.

The overall height is 230mm and they are fixed to the faceplate with 3 screw holes. The top screw hole to the middle screw hole is 110mm and the middle to the bottom is 108mm.

Both the hook and the latch (which features a screw) are 30mm high and the distance between them is 75mm.

When measuring the backset, allow 2-3mm for the faceplate, so a 35mm backset gearbox will measure 32mm when not fixed to the strip.

Ingenious multipoint door gearboxes feature a small, plastic snib on the faceplate. This can be used to hold the latch back for convenience and to prevent accidental lockouts.

Ingenious gearboxes do bear a resemblance to the Fullex XL series (which are also 230mm), so to double-check, we recommend comparing the hook boxes against the pictures as they are distinct.

This gearbox features a 3mm backset and is fitted to Ingenious Duplex locks in Alutech bifold doors.

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