Troubleshooting & FAQ

How do I choose the right roller for my trailer?
First, measure the diameter, width, and shaft size of your existing roller. Next, check our 'Available Models' and 'Technical Specifications' tables to find a match. Pay close attention to the shaft size, as it varies significantly between models (1/2", 5/8", 1-1/8", etc.).

What's the difference between PVC, Polyurethane, and Rubber rollers?
PVC is a hard, durable material that won't mark your hull but is less forgiving on impact. Polyurethane (PU) is stronger than rubber, resistant to cuts, and won't mark the hull, making it a premium choice. Rubber is the softest, offering excellent cushioning, but it can leave black marks and wears down faster.

When should I replace my trailer rollers?
Inspect your rollers regularly for signs of cracking, splitting, or flat spots. A worn-out roller can damage your boat's keel. We recommend replacing them at the first sign of significant wear to ensure smooth and safe loading.
