Genuine Multipoint Gearbox - Lift Lever or Split Spindle

Product Overview: Fuhr Multipoint Door Lock Gearboxes

Fuhr multipoint door lock gearboxes are designed for enhanced security and durability. Key features include:

• Deadbolt Throw: 20mm for standard locks; 14mm for 25mm and 30mm backset locks.
• Gearbox Dimensions: 220mm in length, with a width of 18mm.
• Latch and Deadbolt Height: Both components measure 31mm high, with a 61mm distance between the latch bottom and deadbolt top.
• Screw Fixation: Gearboxes are secured to faceplates using three screws, with specific distances between them: 91mm from the top screw to the middle screw, and 108mm from the middle to the bottom screw.

Enhanced Locking Mechanism

Fuhr locks come equipped with a ball bearing and spring pre-fitted, providing a more positive locking feel. This feature is crucial for ensuring smooth operation. Be cautious of replacement gearboxes that may lack this essential component; all Duffells' replacement Fuhr gearboxes include the ball bearing and spring for seamless installation.

Latch Compatibility

When replacing an existing Fuhr multipoint lock or gearbox, be aware of potential latch height differences. Older models feature a 28mm high latch, while newer versions have a 33mm high latch. If the original latch is intact, it can be reused by removing it from the old gearbox and installing it in the new one.

Special Considerations for Bifold Doors

Pay attention to 30mm gearboxes used in bifold doors, particularly Smarts Aluminium doors, as they are not interchangeable with the standard 856 gearbox.
