The Asec Lockmaster Copy Lever Operated Latch & Deadbolt Twin Spindle Gearbox is a professional-grade replacement unit designed specifically for Lockmaster multipoint locking systems. This centre case gearbox is an ideal, cost-effective solution when only the central mechanism has failed, eliminating the need to replace the entire multipoint lock assembly.

Engineered for versatility, this gearbox features a twin spindle configuration with 92mm and 62mm centres. It is available in two common backset sizes—35mm and 45mm—ensuring compatibility with a wide range of UPVC and composite doors. The unit has a standard case height of 228mm and a case width of either 47mm or 57mm depending on the chosen backset.

Key Features:

  • Reversible Latch: Easily adjusted to suit both left and right-handed doors by simply removing a screw and flipping the latch.

  • Durable Construction: Built to withstand the rigours of daily use, providing secure latching and deadbolt operation.
  • Dual Spindle Operation: Supports lever/lever or lever/pad handle sets for enhanced access control.

To operate, simply lift the lever to engage the locking points and turn the cylinder one full turn to secure the deadbolt. Unlocking is achieved by turning the key and pushing the lever down. This robust gearbox restores your door's security with precision and ease.
