Boat Trailer Blue Roller 2″ Bow Type Poly 13mm Bore – Mini Non-Marking Roller (SKU: CRBB50X13)

The 2″ Blue Poly Bow Roller (CRBB50X13) may be small, but it’s mighty in performance.
Designed for very compact trailers or lightweight watercraft, this roller supports your bow during launch and retrieval without marking the hull.

Its tough poly construction ensures UV resistance, long-lasting use, and smooth guiding even in small-scale setups.

Whether you’re replacing an old rubber roller or building a new setup, this little roller brings solid support where space is tight.

Specifications:

Compact in size, generous in function – a smart choice for trailers with space or weight limitations.
