Make launching and trailering your boat effortless while protecting your hull from costly scratches and gouges. The Yellow Polyurethane 4" x 5/8" Keel Roller Spool is engineered to support the weight of your boat’s keel, absorbing road shock and ensuring a smooth, centered glide every time you head to the water.

Crafted from heavy-duty polyurethane, this spool roller is designed to outlast traditional black rubber rollers. It won’t split, crack, or rot under the harsh sun, and it completely eliminates the ugly black scuff marks that ruin a pristine fiberglass or aluminum finish.

Key Features

• Non-Marring Polyurethane: Protects your boat’s hull by rolling smoothly without leaving unsightly black streaks or marks.

• Weather & Chemical Resistant: Built to withstand UV rays, saltwater, oil, and gas, preventing the cracking and rotting common with rubber rollers.

• Smoother Launch & Retrieval: Spool design naturally guides and centers the boat's keel onto the trailer, even in choppy waters or tricky boat ramps.

• Heavy-Duty Core: Features a solid interior sleeve designed to spin freely on a standard 5/8" roller shaft under heavy loads.
