4" PVC Boat Trailer Roller Bell Yellow 1/2 inch Diameter Bore

This is a yellow bow roller end bell for your standard 4-inch Poly or PVC Boat Trailer winch seat Roller. We sell these individually so you can replace one side if that is what's needed, however, if you're making a Boat Trailer Roller Assembly from scratch you will most likely need two of these bells. The yellow PVC Bell Roller is used to give additional support and protection to your Boat Hull, and they are typically mounted on the ends of the roller shaft outside of the Roller Bracket Arms. This bell will match perfectly with our Yellow 4 inch PVC Bow Roller if you are looking to make your own new assembly for your 4-inch wide winch stand bracket. This requires a longer Roller Shaft or Trailer Bolt to accommodate the addition of the End Bells, but it will leave you with a helpful roller on the inside and outside portion of the Boat Trailer Roller bracket to assist in loading and unloading your boat.
