While moving my trailer around today without the boat, it appears as though the bow roller (the plastic or rubber roller, and the bolt it was mounted on) came off and is lost. The trailer is a two-axle Loadmaster from the mid-1990s, and the winch mounted adjacent to the bow roller is a Fulton T2005. Is there anything I need to know to spec a replacement correctly? Once I measure the width, are they pretty standard beyond that?
