Ingenious uPVC & Composite Door Lock Centre Gearbox Case 35mm & 45mm Backset | Replacement Multipoint Lock
Product Description
Keep your door locking smoothly with this Ingenious replacement centre gearbox, designed for use with uPVC and composite multipoint door locks. If your door handle has become stiff, the key no longer operates correctly, or the lock mechanism has failed, replacing the centre case is often a more cost-effective solution than replacing the complete lock strip.
Manufactured as a direct replacement for compatible Ingenious multipoint locking systems, this gearbox is available in 35mm or 45mm backset options to suit a wide range of door configurations. The reversible latch allows installation on both left and right-handed doors, making fitting quick and straightforward.
Ideal for repairing worn or faulty door mechanisms while retaining your existing locking strip.

Before Ordering
