uPVC Gearboxes
uPVC door locks are often described as multi-point locks, this is because they usually have multiple locking points along the door. uPVC door locks come in hundreds of different variations, with various different locking bolts:
- roller
- mushroom roller
- small hook
- large hook
- dead bolt.
These all work off the main gearbox where the handle is located. There are many reasons why these sometimes don’t move or don’t seem to fit into their prospective slots. If you have a problem with any of these then contact us and we’ll be only too happy to help you out.
