Protect your boat's hull and enjoy effortless launching and loading with a premium, non-marring keel roller.

Make trailering your boat a smooth, stress-free experience with this heavy-duty 4" Yellow Polyurethane Keel Roller Spool. Specifically engineered to handle the concentrated weight of your boat's keel, this spool-shaped roller guides the center of the hull smoothly onto the trailer without friction. Molded from advanced, high-density polyurethane, it is designed to replace old, cracked rubber rollers that rot over time. It provides a rugged, high-capacity bearing surface that cushions your boat while completely eliminating the risk of ugly black scuff marks on your clean fiberglass or aluminum hull.

Key Features

• Non-Marring Polyurethane: Advanced yellow poly construction is entirely non-marking, ensuring your boat's gelcoat and hull stay pristine and free of black streaks.

• Heavy-Duty Spool Shape: Deeply contoured spool design naturally centers the keel during loading, preventing the boat from shifting off-course even in choppy ramps or strong crosswinds.

• Extreme Weather & Chemical Resistance: Unlike traditional rubber, this polyurethane roller will not crack, flat-spot, or dry rot under intense UV sun exposure, saltwater, or oil.

• High-Capacity Low-Friction Core: Features a precision-molded internal bore designed for a standard 1/2" shaft, delivering smooth, frictionless rotation under heavy loads.
