  • Does Dutton-Lainson 4-Inch Boat Trailer Spool Roller DL21566 Contain Metal
    Dutton-Lainson 4-Inch Boat Trailer Spool Roller # DL21566 is made of rubber but it has an inner sleeve made of plastic that provides the internal 5/8-bore size and smooth surface to mate with a roller shaft like # CE10721A. I checked this item myself to make certain. Please refer to the linked photo.

  • Roller Recommendation for Guiding a 2 inch Wide Strap on Boat Trailer
    The best roller for your needs would be the # YR5203-4P this has an overall length of 5 inches so it would work well for a 2 inch wide strap to roll on the inner part of it. The overall diameter of the roller is 3 inches which is pretty close to what you need. It's designed to roll on a 1/2 inch shaft like part # CE10701A. For a bracket you could use the panel bracket part # CE10301G or the angle brackets part # CE10211G. Check out the review video I attached.
