This pull pin and cotter pin set features a 5/8-inch diameter steel construction finished in natural (unplated) steel, delivering robust corrosion resistance and straightforward repairability in field conditions. The pull pin design allows quick, one-handed engagement and removal without requiring tools, making trailer hitch hookup faster and more intuitive during frequent towing operations.

Installation is straightforward: insert the pull pin through the aligned holes in your hitch assembly and secure it with the cotter pin by bending the clip legs around the pin shank. Weighing just 0.6 lbs and measuring 3.05 × 1.4 × 7.35 inches, the compact form factor fits easily in a toolbox, truck bed, or glove compartment for emergency roadside replacement. Mechanics and fleet operators rely on REESE hardware for consistent, no-nonsense performance that withstands thousands of connect-disconnect cycles.
