Fulton Fold-Away Bolt-On Hinge Kit 3" x 3" Trailer Beam, Rating 5,000 lbs., 48" Pivot, Z-Max 600 Zinc Finish

The Fulton Fold-Away Bolt-On Hinge Kit 3" x 3" Trailer Beam with 5,000 lbs. rating is a heavy-duty coupling solution designed for trailer construction, equipment transport, and vehicle recovery applications. This bolt-on hinge kit features a 48-inch pivot point and Z-Max 600 zinc finish, providing corrosion resistance in harsh outdoor environments where trailers face extended exposure to moisture, salt air, and variable weather conditions.

Built to handle 5,000 lbs. working load, the 3" x 3" beam dimension offers the structural rigidity needed for flat-bed trailers, lowboy carriers, and specialized transport equipment. The fold-away design enables compact storage and transport when the hinge is not in use, making it practical for operators who manage multiple trailers or need to maximize yard space. The Z-Max 600 zinc finish provides superior corrosion protection compared to standard plating, essential for trailers operating in marine, agricultural, or construction environments where rust and oxidation compromise structural integrity over time.

This kit serves fleet operators, construction contractors, equipment haulers, and off-road recovery specialists who require reliable coupling hardware rated for sustained load cycles. The bolt-on installation simplifies retrofit applications on existing trailers, eliminating the need for welding and allowing field replacement if damage occurs. A 5-year limited warranty backs the product, providing coverage for manufacturing defects during normal use. The 11 lbs. weight and compact dimensions (7 x 5 x 9 inches) make this hinge kit easy to store and transport as a spare component or replacement unit.
