MACO
MACO Multipoint door locks can be found in Upvc doors. There are two types of Maco gearboxes available; one is the old style and the other is the new style. However, if you have an old style gearbox you cannot change it for the new style; you would have to change your whole multipoint lock. The old style gearbox has either a 28mm or 45mm backset, so if you have a 35mm backset, again you would have to change your lock as they no longer manufacture the 35mm backset gearbox.
As from October 2015 Maco have discontinued a lot of their locks, please call 01332 340446 for alternative locks and to check availability
