Shop our range of high quality Gearboxes from top brands such as ERA, KFV, Maco, Yale and many more. The Gearbox, also known as centre case, is the central part of the multipoint lock strip. This part has the mechanics that operate the locks along the whole strip. Often when your lock fails, it can be fixed by simply replacing the gearbox or centre case, rather than replacing the whole multipoint strip. We have a team of friendly, expert staff who can help with choosing, measuring or fitting any of our products. Visit our technical help page to find the different ways of contacting us with any query.
