These Blue keel rollers are made of stabilised Polypropylene, made for harder style hulls, including alloy. The 'V' shaped roller is designed to work with the centreline of the boat, keeping the boat centred during retrieval and launching.
The rollers are measure by length and bore diameter of 17mm - please ensure you have the correct bracket and spindles required.
When choosing the rollers, it is essential you're picking the correct one for the size, type and shape of your hull. These rollers come in three easy to identify colours;
Blue - Polypropylene construction. Firmest roller, and longest lasting. Only suitable for hard hulls such as Alloy.
Black - Rubber construction. Soft design suitable for lightweight boats.
Red - Polyurethane construction. Firmer than rubber, but still soft enough for fibreglass boats.
*Please note, bore size is approximate. 17mm.
