Today, we're going to review part number DL21554. This is the Dutton Lainson 2-1/2-inch diameter guide-on roller for boat trailers. This 2-1/2-inch diameter roller will replace one of your boat trailer's side guide rollers. It is a heavy duty rubber construction which is strong and durable. This will replace one of the side guide rollers on your boat trailer. It does ease the loading and unloading of your boat.
It will mount along the side of your trailer to better guide your boat into place. This roller is made of a solid high-grade rubber material, and a few dimensions on this. It is 12 inches in length and the diameter is 2-1/2 inches, and the shaft hole size right here is 5/8 of an inch so this will fit on a 5/8-inch shaft diameter. That should do it for review on part number DL21554.
