The Ark Trailer Skid Strip is made of hard, blue polyethylene and measures in at 1.5m x 50mm x 12mm. Hard-wearing and non-marking, it's designed to be used on trailers with skids. It can be used in conjunction with rollers. Boat trailer skids maximise support, and make launching and retrieving your tinny a breeze. One worn or damaged skid can mean the difference between your boat coming on straight and easy, or creating back-breaking problems.
