The adjustable width allows for quick and unobstructed loading of boats of different sizes, including ski boats, sailboats, small fishing boats, and dinghies, ensuring that the boat remains in the correct position without shifting.

The columns are designed with rubber rollers that smoothly roll, effectively guiding the boat loading direction while minimizing friction and wear between the boat and the columns, thus protecting the boat's surface.

These two installation methods are suitable for trailers with different frame widths. The upgraded M8 thickened high-tensile steel material ensures a firm and stable installation without excessive movement or deformation.

The guide rail is coated with a thick, anti-corrosion layer, ensuring corrosion resistance and durability in all weather conditions, even in coastal areas, preventing rusting when exposed to sunlight, rain, or seawater.
