Boat trailer guide 20.5″ adjustable poles

Boat trailer guides that centre and secure your boat during loading and transport. This two-piece set features 20.5-inch tall poles with adjustable width (7.5 inches each side) to fit fishing boats, dinghies, inflatable boats, and canoes of varying sizes.

Rubber rollers on each pole guide the boat smoothly onto the trailer while minimizing friction and protecting the hull from scratches and scuffs. The rollers also help prevent lateral rocking during travel, keeping your boat stable and secure.

The poles are built from high-tensile M8 steel with a thick, durable coating that resists rust, salt spray, and UV damage—ideal for regular use near water. U-shaped bolts attach securely to trailer beams up to 3 inches wide, accommodating most small to medium boat trailer frames.

Installation is straightforward: mount both poles to your trailer beam, adjust the width to match your boat, and you’re ready to load. The heavy-duty construction means these guides will remain stable and corrosion-free season after season.

Measure your trailer beam width and boat hull width before ordering to ensure proper fit.
