This multipoint lock operates using a lift-lever mechanism and is designed for use with a Euro cylinder, making it suitable for both standard and high-security cylinder upgrades.

At the centre of the lock is a latch and deadbolt configuration positioned within a centrally located lock box, ensuring smooth engagement and dependable door closure. The lock features a 35mm backset measurement with a 92mm (PZ) centre a common specification for modern uPVC doors, allowing for straightforward replacement of existing Mila style mechanisms. The faceplate measures 16mm in width and is finished with a square end design, providing a neat and professional fit within the door profile.

The hook to hook measurement is 1185mm, with the top hook positioned 580mm from the centre and the bottom hook 605mm from the centre, ensuring optimal engagement with the door frame keeps.

Lightly lubricating the gearbox and moving components with GT85 helps reduce friction, prevents wear and prolongs the lifespan of the locking mechanism.

Whilst upgrading your multipoint door lock, it is the perfect opportunity to replace your existing cylinder with a high-security 3-star Euro cylinder, significantly improving protection against snapping, drilling and picking. You may also wish to refresh the appearance and functionality of your door by upgrading your door handles, creating a secure and visually stunning finish at the same time. Both options integrate seamlessly with this Mila multipoint lock.
