The mounting brackets for this boat roller sandwich around the trailer's tongue and attach with included 3/8 Inch diameter bolts. Multiple holes in the brackets make it easy to adapt to the different heights of trailer frames and also ensure that the roller will be mounted at the proper position. The 5 Inch thermal-plasticized rubber spool roller helps to support your boat's keel during trailering.
