Adjustable Width of 11.8 Inches: After installing the guide rail, the height is 46 inches, with an adjustable width of 11.8inch/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.

Top Solar-Powered LED Lights: The column's top has been upgraded with solar-powered LED lights, eliminating the need for charging and offering an reliable and hassle-free solution. These lights are highly visible at night, serving as a clear warning to oncoming vehicles and reducing the risk of accidents during transportation. Note: The LED light is flashing, not steady.

Spraying Protection: The metal surfaces are all coated with thickened spraying coating, which is not easy to rust and makes the rails durable for long time outdoor use.

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.
