It has five waterproof lines made of polyester that can be continuously extended to a length of 4 meters. It comes with two hooks for the opposite wall and can be installed almost anywhere, either on a long narrow balcony or in the bathroom. A total drying length of 20 meters can be achieved for two loads of laundry. The big advantage of the Leifheit Rollfix 210 is that it takes up almost no space after use. Just remove the tip and the line retractor will pick up the lines.
