with a 3-inch wide mounting bracket and uses a 1\/2-inch diameter shaft or bolt. Measure your existing bracket and shaft diameter to ensure compatibility before ordering.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat is the benefit of polyurethane over traditional rubber rollers?\u003c\/summary\u003e\n  \u003cp\u003ePolyurethane is a superior material for boat trailer rollers as it is non-marking, meaning it will not leave scuffs on your boat's hull. It is also more durable, resistant to cuts, and holds up better against UV light and saltwater compared to standard black rubber.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhen should I replace my bow roller?\u003c\/summary\u003e\n  \u003cp\u003eInspect your bow roller regularly for signs of wear, such as deep grooves, cracks, chunking, or deformation. Replace it if it no longer spins freely or shows significant damage, as a worn roller can damage your boat's hull during loading and unloading.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs mounting hardware included?\u003c\/summary\u003e\n  \u003cp\u003eNo, this listing is for the roller only.
