The 91100 Ribbed Grey Wobble Roller is a durable polyurethane boat trailer roller designed to support the sides of the boat hull while launching, retrieving and transporting. Its ribbed profile improves grip and allows the roller to rotate with the hull as the boat moves on and off the trailer. The grey polyurethane construction is non-marking and UV resistant, making it particularly suitable for fibreglass boat hulls.

Suitable Applications
- The 91100 is particularly suited to fibreglass boat trailers using wobble-roller or multi-roller support systems.
- Wobble rollers articulate and rotate as the hull travels over them, helping the trailer support the hull contour while reducing resistance during launching and retrieval. Australian suppliers specifically recommend this grey ribbed polyurethane version for fibreglass boats.
Signs Your Wobble Rollers Need Replacing
- Replace worn rollers when they show cracking, splitting, severe flattening, excessive bore wear, missing ribs, seizure on the spindle or uneven rotation.
- When replacing the roller, inspect the wobble roller shaft, bushes, washers, retaining clips and mounting arms at the same time.
