Our mission at House2Home is to provide our customers with the highest quality upholstery supplies for all your DIY projects. Metal webbing clips are commonly found in Danish Modern style furniture and are distinguished by the groove cut in the front and the back rail of the seat. Occasionally there may also be grooves cut on each side of the seat frame with the idea being that the webbing should be installed in a weaving manner. These metal clips simply clamp down on 2" Pirelli, elastic, rubber, and elasbelt webbing, and then the clips simply slide into the groove. Each clip contains four teeth that are designed to bite into the webbing when the clip is clamped down tight. Clamping the clips tight is easiest with a bench vise but can also be done with a pair of vise grips or even standard pliers In the event that your piece of furniture does not have these grooves cut in the frame, the clips can also be installed by screwing the clips directly into the frame.
