The 38mm Roller Blind Repair Kit is designed to restore the functionality of heavy window shades. It features a clutch mechanism supported by a zinc alloy and aluminum drive core, which adds structural rigidity to the assembly. The mounting brackets are made from 1.5mm cold-rolled steel, providing a sturdy foundation for the weight of larger blackout shades.
Practical usability includes a high-tension internal manganese steel spring that assists with smooth operation. The clutch housing is made from PA66 nylon, a material chosen for its ability to handle thermal expansion and resist UV exposure through window glass. This kit is designed to fit standardized mounting holes found in most modern retail brackets, making it a straightforward replacement for worn components.
Usage Guidelines
- This kit is specifically sized for 38mm tubes; ensure the inner diameter of your blind tube matches before installation.
- Compatible with standard 4.5mm x 6mm bead chains to prevent skipping during operation.
- Adding a small amount of silicone lubricant to the gear interface can help maintain a quiet operation over time.
If you are repairing a smaller, lighter window shade, the 28mm version of this repair kit may be more appropriate for your hardware.
