Industrial-grade raw steel weld-on hinge designed for the high-stress environment of dump trailers and freight doors, featuring a built-in grease fitting to prevent seizing.
The DH-2 is the industry standard for "loose-tolerance" hinges, engineered to maintain smooth operation even if a trailer frame flexes or twists under heavy loads. This R&P Carriages weld-on hinge is a high-quality industrial solution designed for applications where standard precision hinges might bind. Its raw steel construction allows for immediate, deep-penetrating welds, making it the top choice for manufacturers and repair shops dealing with heavy-duty tailgate assemblies.
Ensure a long service life for your tailgate assembly with these professional installation tips:
Compatibility: Universal weld-on design for steel frames and tailgates; cross-ref 7356 / TLU32-0004.
Vehicle / System Fit: Dump trailers, Horse trailers, Freight trucks, and Service bodies.
Installation Notes: Multiple hinges must be aligned along the same vertical or horizontal axis to ensure smooth rotation.
Performance Insight: Heavy 5/16" to 3/8" steel plate thickness ensures the hinge will not deform under the weight of heavy tailgates or ramps.
