Viking 4½in Flat Bilge Roller – Black Rubber, 17mm Bore

Bilge roller's worn to a flat line and your boat's tilting to one side every time you back it onto the trailer. Frustrating, and it'll crack a fitting if you're not careful.

This Viking 4½in flat-profile bilge roller (part 91220) sits flush against the hull's bilge line. The flat face distributes load evenly instead of concentrating it on one point, which is exactly what a bilge support needs.

17mm bore means it drops onto your existing bracket. Black soft rubber keeps things simple and affordable. Same honest caveat as the rest of the Viking range: it's a soft compound, so it can scuff a pristine finish over time. For a boat that's been out a few years, that's a small price for a roller that actually holds.
