*KeyFeatures *Adjustable Width of 13 Inches: After installing the guide rail, the height is 27.6 inches, with an adjustable width of 13inch/330mm on each side. This allows for quick and unobstructed loading of small boats such asfishing boats, dinghies, inflatable boats, and canoes of different widths without obstruction, ensuring their proper and secure positioning. *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 small fishing boat trailer models,ensuring a secure installation even on smaller frames. The upgraded M8 thickened high-tensile steel material provides a firm and stable attachment, preventing any wobbling or deformation. *Galvanized Rust Protection: All metal surfaces are coated with a thick, non-peeling galvanized layer, ensuring that the guide rail can be used for extended periods outdoors near the sea. It provides corrosion resistance and all-weather durability, even when exposed to sunlight, rain, or prolonged contact with seawater, preventing rusting. *All-Steel Construction: The brackets are made from heavy-duty steel material, upgraded specifically for outdoor boat loading. The thickened inner walls can withstand boat impacts without easily deforming or bending, ensuring long-lasting durability. *Protecting and Securing Your Boat: The 1.8-inch thick cushioned padding effectively protects the boat's surface. It ensures that there is no metal contact with any part of the boat's body during loading and transportation, preventing scratches and providing effective cushioning against impacts. This padding also helps secure the boat during transportation, preventing lateral rocking. ******************************************************************************************************* *Specifications Item Model Number: XSJ23-F07 Net Weight: 22 lbs/9.98 kg Single-Side Installation Dimensions: 27.6x20.1x20.1 inch/700x510x510 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
