Reese Towpower Coupler Pin with Chain

The REESE Towpower trailer coupler pin and safety chain is designed for multiple uses, but specifically for trailer coupler levers with a 5/16 In. diameter hole. Inserting the pin allows the trailer coupler lever to remain in a safely closed position while in use, or an open position when uncoupling. The safety chain allows for the pin to hang freely while not in use, which is ideal for marine applications.
