Viking 4½in Keel Roller – Soft Red Polyurethane, 17mm Bore (Model 91513)

Your hull's due for a fresh coat and you need a roller that actually conforms to the keel line without leaving ridges. This is the Viking 4½in Keel Roller (91513) in soft red polyurethane, cut on a 17mm bore. It's the one most boat owners reach for when they're working fibreglass hulls — the softer compound picks up and lays down your product evenly without the chatter you get from harder rollers. Fits any standard 17mm spindle. Add to cart and you're rolling this weekend

• 4½in keel profile shaped to follow the hull's lower curve
