Multipoint window espagnolette gearboxes ensure security and smooth operation for UPVC, timber, and composite windows. Essential to multipoint window locking systems, gearboxes engage multiple locking points, providing robust protection and ease of use. At Duffells, we stock an extensive selection of replacement window gearboxes for various window configurations and locking mechanisms, supporting your professional requirements.

Window espagnolette gearboxes operate at the heart of the window espag locking system, controlling the locking points along the window sash. A reliable gearbox is crucial to secure window locking and smooth functionality. Window gearboxes typically actuate mushroom keeps, rollerbolts, deadbolts, or a combination of these locking points.

Duffells stocks window gearboxes from leading manufacturers such as Maco, Winkhaus, Kenrick, Yale, Saracen, Trojan, Roto, Nico, Vitawin, and many others. Our trade-only service gives you direct access to a wide range of window espag gearboxes with same-day despatch, and dedicated support to quickly identify the right window gearbox for your project.

Multipoint window gearboxes differ by locking mechanisms, backsets, and fixing methods:

Espagnolette Gearboxes:

Activate mushroom cams or roller locking points along the espag rod.
Common in UPVC, timber, and composite windows for excellent security and smooth operation.

Deadbolt Gearboxes:

Provide additional strength and robust vertical or horizontal locking.
Ideal for high-security requirements in residential or commercial window applications.

Clip Fit (Bayonet) Gearboxes:

Feature quick installation through push-and-twist bayonet fixing, eliminating screws.
Convenient for rapid replacement and maintenance efficiency.

Screw Fix Gearboxes:

Secured directly with screws, suitable for timber and composite windows requiring stronger fixture methods.

Window Gearbox Backset

The backset measurement (distance from the gearbox faceplate front to the spindle centre) commonly ranges from 20mm to 22mm. Accurate backset identification is crucial when sourcing replacement window gearboxes.

Locking Point Types Multipoint window locks engage various locking points:

Mushroom Cams: Provide firm locking engagement into keeps.
Rollerbolts: Ensure smooth operation and strong sealing.

Combination systems: Blend rollers, mushrooms, and deadbolts for versatile security.
