Boat Trailer 8″ Grey Rubber Parallel Keel Roller – 19mm Bore, Non-Marking (PRGR200X19)

The PRGR200X19 is a solid and reliable 8-inch parallel keel roller designed for trailers using a 19mm shaft. It provides broad, flat support to evenly distribute hull pressure, minimizing damage or warping.

Constructed with 75 DURO non-marking grey rubber, it’s built to withstand harsh marine environments while protecting your boat’s surface. The roller is press-fit mounted, allowing the shaft to rotate within the bracket while the roller remains stationary.
