Buying Guide: Key Purchase Considerations
- Material matters: TPU and polyurethane options provide hull protection and durability; PVC is lighter but may wear faster under heavy use.
- Size and fit: ensure the roller width and inner diameter align with your trailer’s bracket and keel size; measure space before buying.
- Mounting hardware: confirm mounting bolt size (commonly 1/2″), and whether your trailer front bracket supports the bolt pattern.
- Hull protection: look for bow stops that cushion and guide the hull to minimize surface scuffing during loading and unloading.
- Maintenance and environment: consider saltwater resistance and ease of cleaning; avoid materials prone to rust or corrosion.
