The C.E. Smith Post Guide-Ons are a 75 inch pair on pre-galvanized steel, mounting to I-beam trailers and boat lifts.
The mounting clamp is the difference from the U-bolt version. A two-piece clamp works above or below an I-beam, which is what lets the same guide-on suit a trailer frame or a lift structure. It fits I-beams up to 4 inches wide with the hardware supplied, where a U-bolt mount is limited to a boxed frame.
At 75 inches the posts stand above the water once the trailer is submerged, so a ramp can be backed down on sight rather than by feel. Each side adjusts out to 19 inches to suit the beam, and the set of two ships with mounting hardware included. Explore more trailer guides and bunks.
