This Mila copy gearbox has a latch only with a single 8mm spindle. Also known as Coldseal and Swiftlocks. Fixing points are not threaded and will require M4 x 10mm self-tapping screws.

Available in both latch only and latch and deadbolt configurations, with a double or spindle spindle.

Latch only versions are always single spindle and are available in 25mm, 28mm, 35mm and 45mm backsets. Latch and deadbolt versions with a single spindle (92mm PZ) are available in 35mm and 45mm backsets and double spindles are available with a 35mm backset only. The double spindle lock features a 70mm/ 92mm PZ measurement.

Despite the various backsets and operation options, the dimensions of Mila gearboxes are largely the same. They measure 233mm high by the backset + 20mm wide. The latch measures 20mm high, the deadbolt is 30mm high and there is 80mm between the bottom of the latch and the top of the deadbolt.

Please note that some older locks feature an offset, or cranked connector. This is only an issue when replacing a gearbox, rather than a full length lock, but it's an important point to consider. Replacement gearboxes are now only available with inline connectors. They are still compatible with older locks but it will be necessary to adapt the drive gear that runs behind the faceplate. Follow our technical guide on the process, but there is a square hole in the drive gear which needs to be cut to create a slot to ensure that the lock works.
