This full length keep is part of the trusted Yale Lockmaster range and is developed to suit the Lockmaster PL143-19 Unsprung Split Spindle 3 Hook 4 Roller PVC Door Lock.

Ideal for both replacement and upgrade projects, this keep helps restore the integrity of your multipoint locking system, improving both security and ease of use. Over time, door keeps can wear or become misaligned, leading to difficulty in locking or reduced security; replacing with a genuine Yale Lockmaster component ensures your door continues to operate as intended.

While upgrading your multipoint door lock keep, it’s worth considering additional improvements to maximise both security and appearance. This is the perfect opportunity to explore our Door Cylinders range, where upgrading to a high security 3 star cylinder can significantly enhance protection against modern break-in methods. At the same time, refreshing your Door Handles can provide a stunning visual upgrade while ensuring smooth operation and ergonomic comfort.

To maintain the performance of your multipoint locking system, regular lubrication is recommended. Applying a high-quality lubricant such as GT85 to the gearbox and moving components will help reduce wear, prevent stiffness, and extend the lifespan of your lock. Routine maintenance ensures consistent operation and avoids unnecessary strain on the locking mechanism.
