To pass through the door handle

The through-handle for PVC doors and windows is a core operating component designed specifically for PVC door and window systems, engineered to deliver seamless functionality, durability, and user-friendliness.

Constructed with a robust through-type linkage structure, the handle connects the inner and outer sides of the door or window, enabling synchronized operation—when one side is turned or pulled, the other responds instantly, ensuring smooth and consistent control during opening and closing. This eliminates the hassle of adjusting both sides separately, making it intuitive for users of all ages.

Crafted from high-quality materials such as zinc alloy or high-carbon steel, the handle undergoes advanced surface treatments including electrophoresis and powder coating. These processes enhance its resistance to corrosion, UV radiation, and daily wear, ensuring long-term performance even in humid or exposed environments. With a tested service life of over 100,000 cycles, it maintains structural integrity against warping or breakage, making it suitable for both residential and commercial applications.

Designed for universal compatibility, the handle accommodates various PVC profile sizes (e.g., 60mm, 80mm, 90mm) with pre-calibrated hole distances, allowing for straightforward installation without the need for additional modifications. It integrates seamlessly with mainstream PVC door and window brands, reducing installation time and costs for manufacturers and contractors.
