Fold-Away Bolt-On Hinge Kit 3in x 3in Trailer Be

The Fold-Away Bolt-On Hinge Kit 3in x 3in Trailer Beam is a heavy-duty tongue hinge assembly engineered for utility trailers, equipment haulers, and custom vehicle builds requiring reliable load distribution and easy access. Designed by REESE, a trusted name in towing hardware, this bolt-on hinge eliminates the need for permanent welding while maintaining structural integrity under demanding conditions. Whether you're setting up a new trailer bed, upgrading an existing frame, or fabricating a custom cargo platform, this kit addresses the critical need for a secure, repeatable connection point that can withstand significant stress cycles.

Built from zinc-plated steel, the Fold-Away Bolt-On Hinge Kit features a 5000-pound maximum weight rating and accommodates 3-inch by 3-inch trailer beam cross-sections, making it compatible with standard square tube construction found across commercial and DIY applications. The fold-away design allows the tongue to collapse downward for storage, loading convenience, or tight parking situations—a practical advantage over fixed hinges. Complete mounting hardware is included, eliminating the need for sourcing fasteners separately. The zinc plating provides corrosion resistance essential for trailers exposed to road salt, moisture, and weather, extending service life while reducing maintenance demands on your vehicle or equipment setup.

Mechanics and fabricators benefit most from this kit when reinforcing lightweight trailers, converting flatbeds, or replacing worn hinges on existing rigs without full-frame disassembly. Installation is straightforward: align the hinge arms to your 3x3 beam, bolt through the pre-drilled holes, and secure with the supplied hardware. The 10.8-pound unit ships in compact 7.15 x 5.15 x 8.8-inch packaging, making it practical for both professional shops and garage builders. Verify your trailer beam dimensions match the 3x3 specification before purchase; oversized or undersized frames will require alternative hinge solutions or custom fabrication.
