4" Smooth Wobble Roller 20mm Bore | Red Blue Black

4" smooth wobble roller for boat trailer side arms. Soft polyurethane, 20 mm bore. Choose red, blue or black.

The smooth face self-aligns on the hull as the boat comes on and off. Softer than old rubber wobble rollers, so it is kinder to gelcoat and alloy plate and lasts longer in sun and salt.

Where it goes

• Side wobble-roller arms and multi-roller banks
• Fibreglass and plate-aluminium hulls
• Replacing cracked or flattened 4" rubber rollers

This is not a bow / winch-post keel roller. For the front of the trailer use a bow or V roller.
