Boat Trailer 8″ Blue Polyethylene Self-Centering Keel Roller – Non-Marking (SKU: SCBB200X21)

This 8″ Blue Self-Centering Keel Roller (SKU: SCBB200X21) is a durable, firm-support roller made from high-quality non-marking polyethylene. It’s built for aluminium and fibreglass boats where maintaining a clean hull surface is crucial. The self-centering design ensures your boat glides smoothly onto the trailer, reducing stress and making solo launches much easier.

The firm plastic construction provides long-term durability and excellent support for mid-sized boats. Unlike rubber, this roller won’t absorb water, crack, or develop flat spots, and the non-marking surface keeps your hull looking clean and new.

Perfect for boaters who want strength, clean contact, and consistent performance. Whether you’re replacing worn-out rollers or outfitting a new trailer, this one gets the job done—without leaving marks.
