item has designed Profiles 8 R for building clean and elegantly rounded constructions. They feature two closed sides that keep dirt and dust out. Depending on the model, profiles can be connected to the open grooves at an angle of 30, 45, 60 or 90 degrees. This makes the profiles ideal for building hoods, racks and tables with rounded outside edges. As a result, structures have a more attractive visual appeal and present less of an injury risk if anyone knocks against them. The radii also enable users to construct struts to reinforce frames.
