Product Overview: Fuhr 935 Stable Door Multipoint Lock

The Fuhr 935 Stable Door multipoint lock is designed for versatility and security, featuring a combination of 1 Roller, 1 Hook, 1 Deadbolt, and 1 Latch. This innovative locking system allows for independent operation of the door's top and bottom sections, making it ideal for maintaining ventilation while ensuring safety for pets and children.

Key Features:

• Dual Operation: The lock operates in two halves, allowing the top section to open independently for ventilation or interaction with guests, while the bottom section can be used for standard door operation.
• Robust Mechanism: The lock consists of two locking mechanisms that can function independently or together. A specially designed right angle bracket enhances the strength of the interlocking sashes.
• Top Section: The 859 series split spindle operation lock includes a hook, roller, latch, and deadbolt.
• Bottom Section: The 855 series key-operated lock features a bottom shootbolt, hook, roller, and key-operated deadbolt, but no latch.

Specifications:

• Gearbox Dimensions: The top section features a split spindle gearbox, while the bottom section is key wind. Both have a deadbolt that throws 20mm. The gearbox dimensions are 220mm x width + 18mm.
• Latch and Deadbolt Heights: The latch (top section only) and deadbolt are both 31mm high, with a 61mm distance between them. Gearboxes are secured to faceplates with three screws, with specific measurements for screw placement.
• Enhanced Locking Feel: Fuhr locks come with a pre-fitted ball bearing and spring, providing a more positive locking experience. Replacement gearboxes from Duffells include these components for easy installation.

Compatibility Note:
