If the manual sun shading with strap can no longer be opened or closed, you need to repair the roller shutter hinge. This is because the hinge is used to operate the Roller Shutters and is a wearing part. Frequent raising and lowering wears out the roller shutter strap so that it can break over time - often exactly when you need it the least. In many cases, however, the roller shutter strap can be easily repaired or replaced without having to replace the entire roller shutter.

Operate Roller Shutters manually with Roller Shutters Belt

The roller shutter belt - or roller shutter hinge - is an integral part of manually operated roller shutters. By pulling the strap up and down, the roller shutter curtain can be operated quickly and easily.

The belt connects two important components of the system:

The roller shutter shaft in the box, on which the curtain is rolled up when open
And the belt winder, which holds the belt.

When the belt is pulled, the shaft in the Roller Shutters box rotates and the blind opens along the Roller Shutters guide rail. If you release the strap and allow it to slide upwards, the sun shading closes in front of the window. This operation requires little effort and is easy to operate. For highly functional heat, privacy and glare protection that can be quickly adjusted to the position of the sun and requirements at any time.
