Troubleshooting & FAQ

Q: How do I confirm this roller will fit my trailer?

A: Measure the inside width of your trailer's winch post bracket; it should be 3 inches. Also, confirm your existing mounting hardware uses a 1/2-inch diameter shaft or bolt. These are the two most critical measurements for a correct fit.

Q: What is the advantage of polyurethane over a standard black rubber roller?

A: Polyurethane is a significantly more durable material that is highly resistant to cuts, abrasions, and UV damage from sunlight. Unlike rubber, it will not leave black marks or scuffs on your boat's hull and will not crack or split over time.

Q: Is the mounting shaft/bolt included with the roller?

A: The inclusion of mounting hardware varies. This package contains the roller only. Please verify with your specific retailer whether the shaft or bolt is included with your purchase, as it may be sold separately.
