GU Old Style Gearbox Door Lock Centre Case Replacement 45mm

GU Old Style Gearbox Door Lock Centre Case Replacement 45mm. If the locking mechanism on your door is not working, you may not need to replace the full lock strip, it may just be a matter of replacing the centre case gearbox. Replacing the gearbox rather than having to buy a complete new lock is cost effective, and is a relatively easy thing to do. Before ordering carefully measure the Backset and the Lock Handle Centre (PZ) on the old gearbox to ensure a correct fit.
