Alpro 5222 Hookbolt Replacement Gearbox
The Alpro 5222 Hookbolt Replacement Gearbox provides security for a variety of aluminium doors including swinging and sliding applications. The Gearbox is the part that is most likely to be at fault when the door lock fails and becomes unusable. Replacing the gearbox is cost effective as it saves having to buy a complete new door lock. Please refer to the diagram when measuring to ensure the correct fit. The hook bolt is constructed from stainless steel and is a 5 ply laminated construction, with the centre core case hardened, complete with hardened roll pin to resist hacksaw attack. All locks are designed to accept standard 17mm profile euro cylinders or thumbturns. Should you need any help in measuring or fitting any of our products, please contact us.
