*KeyFeatures *Adjustable Width of 11.8 Inches: After installing the guide rail, the height is 43 inches, with an adjustable width of 11.8 inches (300mm) on each side. This allows for quick and unobstructed loading of small boats such as jet skis, sailboats, small fishing boats, and dinghies, ensuring that the boat remains in the correct position without shifting. *Two Installation Methods: The U-shaped bolts can be flexibly installed on trailer beams with a width of up to 3 inches. These two installation methods are suitable for different trailer models, including ski boat trailers and fishing boat trailers. Even smaller frame trailers can be securely mounted. The upgraded M8 thickened high-tensile steel material ensures a firm and stable installation without excessive movement or deformation. *Galvanized Rust Protection: The metal surfaces are coated with a thick, anti-corrosion galvanized layer, allowing the guide rail to be used outdoors near the sea for extended periods. It offers corrosion resistance and all-weather durability, even when exposed to sunlight, rain, or prolonged contact with seawater, preventing rusting. *All-Steel Construction: The bracket is constructed from heavy-duty steel material designed for outdoor boat loading. Its thickened inner walls can withstand boat impacts without easily deforming or bending, ensuring long-lasting durability. *Protecting Boat Surfaces: The PVC column effectively protects the boat's surface, ensuring no metal contact with the boat's body during loading and transportation, preventing scratches and providing effective cushioning against impacts to maintain the column's shape. The higher design also serves as a clear warning to oncoming vehicles, making it easier to observe the trailer's condition during transport. ******************************************************************************************************* *Specifications Item Model Number: XSJ23-F01 Net Weight: 19.2 lbs/8.7 kg Single-Side Installation Dimensions: 21.7x3.3x43.5 inch/550x85x1105 mm ******************************************************************************************************* *Pakcage Content Boat Trailer Guide x 2pcs M8 U-Bolts x 4 M8 Lock Nuts x 8 Spring Washers x 8 Flat Washers x 8 U-Groove Gaskets x 2 Open-End Wrench x 1 User Manual x 1
