Keep your uPVC windows operating smoothly with our range of Saracen Aubi window gearboxes, designed to replace worn, damaged, or faulty locking mechanisms. Whether your window has become difficult to lock, the handle no longer engages correctly, or the internal gearbox has failed, our collection includes high-quality replacement Saracen Aubi gearboxes to help restore your window's security and performance.
Saracen Aubi gearboxes are commonly fitted to a wide range of uPVC casement windows and are engineered for reliable locking and long-lasting durability. Replacing only the gearbox is often a cost-effective alternative to replacing the complete window lock, helping you save both time and money.
Our range includes a variety of backset sizes, spindle lengths, and gearbox configurations to suit different Saracen Aubi locking systems. Each product features detailed measurements and photographs, making it easier to identify the correct replacement before ordering.
