More Than 30 Years of Experience and Global Trust With more than 30 years of manufacturing experience, Windoform is a preferred solution partner in the door and window hardware industry worldwide. Closely following the changing needs of architecture, our brand is redefining industry standards with the "Jumbo Sliding Handle" series developed for aluminium and PVC sliding systems.

Strong Build, Jumbo Size and Ergonomics From patio doors to wide terrace openings, the user experience is critical in heavy, large sliding systems. Thanks to its enlarged body and ergonomic shape, the Windoform Jumbo series offers maximum grip and comfortable use even on the heaviest sashes. Its modern design with minimal, crisp lines adds aesthetic value to architectural projects.

Technical Advantage: 8-Position Acoustic Mechanism What sets our product apart is its precision-engineered internal mechanism. The special 8-position acoustic gear system gives a solid click and a clear transition with every movement of the handle, letting the user feel its quality. This mechanism not only provides acoustic satisfaction but also extends the product's service life for lasting durability.

Aesthetic and Economical in One Matching all kinds of interior and exterior decoration with eye-catching colours and high surface quality, Windoform Jumbo handles are made on the principle of "accessible quality". For construction companies and manufacturers, they offer strength and aesthetics at the best price, increasing the cost efficiency of your projects.
