Description

The CURT 21578 is a 5/8" hitch pin and clip designed for 2" receiver tubes. It secures ball mounts and other receiver tube inserts, featuring a bent handle for an easier grip. This hitch pin is protected by a black zinc-plated finish for resistance to rust and corrosion.

It provides reliable installation for any ball mount or hitch-mounted accessory with a 2" shank. This makes it a perfect fit for class 3, 4, and 5 trailer hitches. The pin comes with a standard retainer hole to accept the included clip. CURT offers a limited lifetime warranty on this product, with a one-year warranty on the finish and parts.
