• Adjustable Width: The width of this boat guide-on can be easily adjusted, extending to 17 inches at most. It fits any trailer frames less than 3" wide and 4-1/4" tall.
• Flexible Installation: Our trailer guide-on can be mounted on top of the frame or below it, and the U-bolts fit both large frames and smaller frames.
• Solid Construction: These square tubes are made of sturdy galvanized steel and are powder-coated, so they work great against saltwater and do not easily rust.
• With PVC Posts: The two PVC pipes with end caps can be fixed firmly onto the tubes, and they will prevent the boat from being scratched. Add the frames effortlessly and keep your boat protected.
• Wide Application: These boat trailer guides are suitable for ski boats, fishing boats, or sailboat trailers, and they makes loading the boat so much easier.
