The Schellenberg Company offers different screw on belt winders in various designs as well as in the color white or brown. The belt winder is compatible with roller shutter belts with a width of 14 mm or 23 mm. With the various distance between holes (0.8 cm to 17.0 cm) you can choose the belt winder that works best in your home. Some models even include a roller shutter belt.

With the easy to open Flexo Screw-on Belt Winder from Schellenberg you can use the previous mounting holes for your new belt winder. With its practical attachment method the Screw-On Belt Winder Flexo works with distance between holes of 14cm to 15.5cm. The white Flexo Belt Winder from Schellenberg is most compatible for roller shutter belts with a width of 14 mm and a length of 16 feet. A shutter belt is not included in delivery; therefore your previous roller shutter belt can be used. This simplifies the replacement of your belt winder as the opening of your roller shutter box is not necessary. A further installation simplification: your previously used roller shutter belt can be effortlessly attached to the Schellenberg Screw-on Belt Winder Flexo, as the belt winder box can be opened. Simply attach the Schellenberg Screw-on Belt Winder Flexo MINI on the window frame or the wall (surface mounting).
