For smaller roof areas, it is worth pre-profiling to form an SPM profile, but closing by hand is more economical than closing with a machine. With the WFSCH ST, the angle fold can be closed easily, quickly, cleanly and effortlessly while standing. The handles can be adjusted in 3 lengths. This enables optimal use and transport.

Designed for small roof areas, it is efficient to use and can adjust to 4 different
lengths. 8.66" wide
