Yale Lockmaster PLSP72 45mm 3 Deadbolt Multipoint Door Lock

The Yale Lockmaster PLSP72 45mm 3 Deadbolt Multipoint Door Lock is designed to offer dependable security, smooth operation, and long-lasting durability for uPVC, composite and timber doors. Built by Lockmaster, a brand recognised for precision engineering, this multipoint system features a Euro Cylinder configuration with a lift-lever operation, making it straightforward to engage multiple locking points in one motion. Its central lock box incorporates both latch and deadbolt functionality, positioned at the centre of the mechanism for optimal alignment and performance. The 45mm backset and 92mm (PZ) centre ensure compatibility with a wide range of modern door setups, while the single-spindle design provides simple, reliable handle functionality.

This model includes three deadbolts in total—one within the central case and two additional deadbolts positioned at 703mm above the centre and a bottom deadbolt 732mm below the centre respectively, giving a deadbolt-to-deadbolt measurement of 1435mm. These reinforced locking points significantly improve the door’s resistance to forced entry. The 16mm square-end faceplate has an overall length of 2200mm, ensuring a clean, secure fit along the full door edge without the need for extension pieces. Because the Lockmaster PLSP72 is non-extendable, its solid, continuous steel construction maintains structural integrity and enhances reliability over time.

Maintaining your multipoint lock is essential for long-term performance, and applying a light spray of GT85 to the gearbox and moving components helps preserve smooth operation and minimise wear. Regular lubrication contributes to consistent locking action and reduces stress on the handle and internal parts.

While upgrading your multipoint door lock, it’s the ideal time to consider replacing your euro cylinder with a high-security 3-star cylinder for improved protection against snapping, drilling, and picking. You can also elevate your door’s appearance by exploring our door handles range, giving your entrance a clean, refreshed look that complements the new lock installation.
