The Chafe-Mat™, constructed with an outer layer of abrasion resistant ballistic nylon and soft porous underside, is an anti-chafe device that protects the boat’s finish or wood rails from fender lines or mooring lines. Installation is simple, slip the Chafe-Mat™ over the boat’s cleat and then tie the fender or mooring line to the cleat. The Chafe-Mat™ will take the abrasion caused by the lines. To prevent the Chafe-Mat™ from slipping out of position, Chafe-Pro ®’s proprietary material, ShoreGrip®, is located on the underside holding the mat in place. When getting underway, the Chafe-Mat™ is easily removed when the lines are taken in. For those who like a little personalization to their accessories, look no further! Chafe-Pro® offers custom embroidery for a reasonable fee.
