Viking 6in Self-Centring Red Polyurethane Roller – 17mm Bore (91540)

Fibreglass hull? You want the softer polyurethane surface. This red roller is the go-to for fibreglass boats because it grips the gel coat without scarring it. Self-centring keeps it tracking straight when you're fully loaded and backing onto a ramp – no more constant re-aligning after every launch. 6-inch width, 17mm bore. The most common size for smaller boat trailers

• 6-inch roller with 17mm bore for standard trailer shafts
• Softer red polyurethane surface – ideal for fibreglass hulls
