The handle length (palm) is 100 mm, and the handle width is 20 mm.

Yes, the mounting screws are included in the set.
While designed for windows and patio doors, its primary benefit is for internal window operation and security. For exterior doors, weather resistance should be considered.
Measure the square drive size of your current mechanism (this handle uses E7) and the distance between mounting screws. The rosette dimensions are 60 mm x 28.5 mm.
The product information states that Kotarbau items are tested multiple times and suitable for industrial and private use, implying durability. Specific warranty details are not provided in this data.
Check that the mounting screws are fully tightened. Ensure the square drive is properly seated in the window mechanism.
Verify that the square drive is the correct size (E7) and fully inserted. Check the window mechanism itself for any obstructions or damage.
Ensure the rosette is correctly positioned to cover the mounting screws. The screws are designed to be pinned behind the rosette for a clean finish.
Setup: The handle is designed for straightforward installation. Align the handle with the existing mechanism on your window or patio door. Insert the included mounting screws through the pre-drilled holes on the rosette and into the window frame. Tighten securely. The internal pinning of screws means they are hidden once installed.
Compatibility: This handle features a universal design and is intended to fit most standard window types, including uPVC, aluminum, and wooden frames, whether they are new installations or older models. The square drive is E7, and the rosette dimensions are 60 mm x 28.5 mm. It's recommended to measure your existing window mechanism's square drive and the distance between mounting holes to ensure a perfect match.
Care: To maintain the handle's finish and functionality, clean it periodically with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the surface. Ensure screws remain tight over time to guarantee optimal performance.
