8″ Boat Trailer Keel Roller – Blue Dog Bone Nylon, 190mm x 17mm, UV-Stable Plastic (SKU: CRBS200X17)

8″ Blue Nylon Dog Bone Keel Roller – Lightweight, Durable, and Smooth

The CRBS200X17 is a blue polyethylene dog bone keel roller designed to guide your boat smoothly onto the trailer. At 190mm in length with a 17mm bore, it suits standard 16mm shafts and fits most trailer setups.

Its HDPE plastic body is UV-resistant and won’t mark your hull, making it perfect for fibreglass or aluminium boats. The tapered dog bone shape ensures centring performance, helping prevent your boat from drifting during winching.
