8" Concave Roller Red 21mm

These rollers are made of a softer red polyurethane plastic that is less abrasive, non-marking and tougher than rubber alternatives, making them an ideal upgrade for your boat trailer if you wish to optimise stability while in transit and ensure an easy launch/retrieval. Typically designed for fibreglass boats. If your boat is aluminium we recommend using our Hard-Polypropylene Blue Rollers.
