GU Old Style 40mm Replacement Multipoint Door Lock Gearbox – Lift Lever Operation
GU Old Style 40mm Replacement Multipoint Door Lock Gearbox – Lift Lever Operation
Product Information
This high-quality copy replacement gearbox is designed for the original GU Europa multipoint door locks. It is available in multiple backset sizes: 30mm (measuring 28mm when used with a cranked faceplate), 35mm, 40mm, and 45mm.
The gearbox features a latch and deadbolt mechanism with a case height of 208mm (excluding fixing lugs) and a width of backset + 19mm. Key measurements include:
- Latch height: 32mm
- Deadbolt height: 35mm
- Distance between latch and deadbolt: 54mm
- Screw positions: 108mm from top to middle, 92mm from middle to bottom
The 8mm single spindle follower design varies by backset — the 30mm version has a thicker surround, while the 35mm to 45mm versions have a thinner one. When measuring the backset with the gearbox removed, allow for a 2mm adjustment.
Note: This replacement gearbox is only available in lift lever operation. Split spindle and fast locking functions are no longer supported. If your lock uses one of those, you will need a new full-length GU multipoint lock.
We stock a wide range of GU Europa compatible parts, including keeps, spindles, handles, and other door hardware accessories.
