GU Ferco 28mm 4 Roller Multipoint Door Lock

The GU Ferco 28mm 4 Roller Multipoint Door Lock is engineered to restore dependable, smooth and secure operation to your uPVC entrance door. Built around a centre-positioned lock case featuring a latch and deadbolt configuration, this euro-cylinder-driven system uses a lift-lever action to engage all locking points simultaneously, offering both convenience and enhanced protection. Its 28mm backset and 92mm centre ensure compatibility with a wide range of modern uPVC doors.

A robust 16mm square-end faceplate provides a stable and durable mounting surface. Measuring 2285mm in overall length, the unit includes four precisely placed rollers designed to improve sealing, boost weather resistance and reduce draughts. The roller-to-roller measurement of 1610mm ensures strong compression along the height of the door, helping achieve a consistent and secure fit. This lock is fully extendable, making it suitable for a variety of door heights and ensuring easier installation or replacement when upgrading an older or worn mechanism.

Routine care helps prolong the lifespan of any multipoint mechanism, and it is recommended to lightly lubricate the gearbox and moving parts with GT85, which provides a clean, moisture-repelling finish that keeps the internal components operating smoothly throughout the year. When replacing a multipoint lock, many customers also take the opportunity to upgrade related security hardware. It’s an ideal moment to fit a high-security 3-star door cylinder, providing protection against modern lock-snapping techniques, or to refresh the door’s appearance by installing new door handles for a cleaner, more visually appealing finish.
