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.

These two installation methods are suitable for small fishing boat trailer models, ensuring a secure installation even on smaller frames.

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.
