Rollers in general are essential to the loading and unloading process. Not only can they ease the process, but they also protect your boat from impacting the trailer at crucial points. Trailer Rollers are placed at important points on your boat trailers cross-member, typically along the center-line of the trailer. These rollers prevent damage to the boat and assist in support of the boats hull while trailering, loading, and unloading.
