Trailer Door Hinge Aluminum Butt 5×4.75 Heavy Gauge Welded Pin Kay

Description

Product Overview

The Kay Aluminum Butt Hinge is engineered for demanding trailer applications where strength, durability, and ease of service are paramount. Constructed from high‑grade aluminum with a mill‑finished surface, the hinge resists rust and corrosion even in harsh weather conditions. The heavy‑gauge material, measured at .188 inches, provides a solid foundation that can support the weight of cargo, livestock, or equipment without flexing or warping. A removable steel pin, plated for added protection, allows quick disassembly for inspection, lubrication, or replacement, reducing downtime and maintenance costs. The hinge dimensions of 5″ wide by 4″ long fit standard rear ramp doors, horse trailer doors, and cargo utility doors, making it a versatile component across a range of trailer types. Each unit ships as a single piece, ready for either welded installation or drilled‑hole mounting, giving installers the flexibility to choose the method that best suits their fabrication process.

Usage

Designed with the professional trailer builder and the DIY enthusiast in mind, this hinge excels in a variety of real‑world scenarios. For agricultural producers, the hinge provides a reliable pivot point for horse trailer doors, ensuring safe and smooth operation when loading and unloading animals. In the logistics sector, the hinge’s robust construction supports heavy cargo doors on flatbed trailers, allowing quick access to goods while maintaining structural integrity during transit. Outdoor adventure enthusiasts will appreciate the hinge’s resistance to salt‑air corrosion, making it ideal for marine‑influenced environments where trailers are frequently exposed to sea breezes. The removable pin feature simplifies field repairs; a simple cotter pin can be inserted to secure the hinge temporarily, enabling continued use until a permanent fix is applied. Whether mounted by welding directly to the door frame or installed with pre‑drilled holes, the hinge adapts to the specific structural requirements of each trailer design.
