The Drotto forward bracket is only for trailers that do not have any adjustments on the winch stand and the boat needs to be moved forward 2 – 4 inches. 99% of trailers do not need this forward bracket. This setup is extremely rare, but we understand in some cases the boat must be moved back due to trailering issues or being able to fit the boat in the garage if you have no room to spare. This piece mounts to the latch, then mounts to the trailer. It comes in 2 sizes, one for the (3″ and Ranger) and one for the Large model.
