This hot dipped galvanized boat trailer V-guide on will help guide the bow of your boat to center up on your trailer. Made out of 1/8 galvanized steel, sleeved with 2 pvc and caps, this v-guide will save you time when loading your boat on your trailer. Rough width from Tip to Tip is 42 inches. The V guide will attach to your trailers cross-members by using a 2" galvanized hat bracket and two 1/2 x 3" x 4 5/16" galvanized U-bolts that are included in this kit. This Kit is specifically designed to mount on a 3" x 3" front cross member. This mounts on the front beam to support and lift the bow of the boat right before it would make contact with the winch post. As this is typically the point where a boat would go left or right in difficult situations, having additional guiding is ideal to make the loading process easier.
