GU Ferco Original 35mm 3 Deadbolt Multipoint Door Lock

The GU Ferco Original 35mm 3 Deadbolt Multipoint Door Lock is a premium replacement locking mechanism designed to deliver dependable security, smooth operation and long-term reliability across uPVC, composite and timber doors. Manufactured by GU Ferco, a trusted name in door hardware, this multipoint lock is engineered with a euro cylinder lock type and a latch and deadbolt locking configuration to provide strong resistance against forced entry while maintaining effortless daily use.

This model features a centred lock box position and operates using a lift lever system, ensuring all three deadbolts engage securely into the keeps when the handle is lifted. With a 35mm backset measurement and 92mm (PZ) centre, it is ideally suited to many modern door profiles requiring precise alignment and compatibility with standard door furniture. The faceplate is finished with a square end design and measures 16mm in width, delivering a clean, professional fit within the door edge.

Security is enhanced through the inclusion of two additional deadbolts alongside the primary locking point, creating a total deadbolt span of 1606mm from top to bottom. The top deadbolt sits 736mm from the centre, while the bottom deadbolt measures 870mm from the centre, all within an overall lock length of 2285mm. This creates even pressure across the full height of the door, reducing warping, improving weather sealing and dramatically increasing resistance against forced entry.

This multipoint door lock uses a single spindle configuration and is non-extendable, making it ideal as a direct replacement for existing GU Ferco mechanisms with matching specifications. Its precise engineering allows for smooth locking performance and consistent engagement with the frame keeps, helping to extend the lifespan of the door and improve overall security.

For long-term performance, regular maintenance is recommended. Lightly lubricating the internal gearbox and moving components with GT85 on the moving components is recommended to preserve smooth operation and prevent premature wear, especially in the gearbox area where consistent movement occurs.

Upgrading your multipoint lock also creates an ideal opportunity to refresh other door hardware. Many customers choose to replace their Euro Cylinder at the same time, opting for a high-security 3-star cylinder for improved protection. You may also want to explore our door handles, allowing you to elevate the visual appeal of your entrance while ensuring full compatibility with your new lock. Both options offer an easy, natural enhancement during installation and contribute to a complete security and aesthetic upgrade.
