This is for a single Stoltz End Cap or End Bell, in case you have one that needs replacing, if you are creating your own Stoltz Bow Roller Kit, you would need 2 of these bells, one for each end. Remember to use a longer Trailer Bolt or Roller Shaft when adding End Caps or Bells to your Rollers. This Bell requires a 1/2 inch Bolt to fit through its center bore. This is made of the same top quality Polyurethane that all Stoltz Products are made from and it won't mark up your boat or dry rot in the sun like rubber does.
