Boat Trailer Guides, 2-Pack Steel, 30 mm Adjustable Pads

Boat trailer guides keep your pontoon aligned for faster, lower-stress loading while protecting the hull from scuffs. Extra-wide padded guide-ons create a larger contact area to center the boat on bunk-style trailers in crosswinds or shallow ramps. Built from reinforced steel with a galvanized finish for freshwater use, each guide adjusts up to 30 mm for a secure, custom fit on L-beam, box, or C-channel frames.

• Delivers easier centering with extra-wide thick pads that guide the hull onto the bunks.


• Protects finishes with soft, non-slip fleece-covered wood pads to help prevent scratches.


• Adjusts fit with up to 0–30 mm (0–1.2 in) width adjustment per guide for precise alignment.


• Fits common frames up to 3 in wide and 4-1/4 in tall; works with L-beam, box, or C-channel.


• Includes hardware with high-strength M10 U-bolts and a complete install kit for secure mounting.

When loading gets tricky, these adjustable trailer guide-ons add the visual and physical reference you need to line up consistently and avoid rubbing the hull against the trailer. The heavy-duty steel build resists bending from everyday bumps at the ramp, while the top cap helps reduce rainwater entry. Choose between two mounting options to match larger or smaller beams and dial in the width for your setup. Grab yours today and make every launch and retrieval more controlled.
