Mounts on the front of most A-frame boat trailers to prevent the bow of the boat from swinging to either side of the trailer. Since the rubber rollers touch both sides of the boat, it is impossible to miss the winch stand. 3" height adjustment. 4-1/2" side-to-side adjustment. Fits trailers up to 5" high and 2" wide. Made in USA. Per pair.
Colors: White (not shown) or Black.
