1.Adjustable Width: The width of these trailer guides can be easily adjusted, extending to 11 inches at most. They are compatible with trailer frames less than 3" wide and 4-1/4" tall.
2.Flexible Installation: Our trailer guide-ons can be mounted on top of the trailer frame or below it, and the U-bolts fit both large frames and smaller frames.
3.Solid Construction: These brackets are made of 0.12" thick steel and are powder-coated, so they work great against saltwater and do not easily bend or rust.
4.With Carpet-padded Boards: The two carpet-padded boards can be fixed firmly onto the brackets, and they will prevent the boat from being scratched.
5.Widespread Use: These boat trailer guides are suitable for ski boats, fishing boats, or sailboat trailers, and they make loading the boat so much easier.
