This roll is approximately 100 feet long, though the manufacturer has a +/- of 10ft, so the actual roll lengths will vary from about 90ft to about 110ft. The Carpet will arrive in one continuous roll, to be cut easily to length when it arrives. This is 15 oz weight Black Bunk Board carpet without backing. Having No Backing allows this carpet to withstand significant force and boat hull wear, while still allowing excellent moisture dissipating capabilities. This makes this carpet ideal for very abrasive use. In addition, carpet without backing is ideal for use on light to heavy duty applications, such as boat bunks and boat lifts. This carpet is cut to this 18" width from a much wider sheet of Marine Carpet. This Carpet is easily installed with Staples or Bunk Carpet Nails, and is ideally used on 2" x 4" or 2" x 6" Bunk Boards on Boat trailers and Boat Lifts. This bunk carpet allows for minimal water retention and maximum weather resistance. This trailer carpet performs extremely well in saltwater as well as freshwater. Having properly functioning bunk carpet is crucial for protecting your boats hull from damage. Heavy duty bunk carpet prevents pre-mature tearing and will keep your boats hull from making contact with your bunk boards. This Boat trailer Bunk Carpet is what an OEM would use, so in most cases is the same carpet that came with the boat trailer right from the Manufacturer.
