This washer plays the role of a distance between intersecting beams as well as pipes and profiles. Now you can connect round and square beams, screw HDPE boards, planks, plywood and other flat elements to them. An additional advantage is the ability to combine two elements at any angle. It prevents jamming by eliminating dangerous, narrow inter-bubble spaces. Available size - Φ35 R16 fits tut Φ 32-33,7 mm. They are produced in 5 basic colors - yellow, red, blue, green, black; but at customer's request we will make any other color. Material: Polyamide PA.
