Master Lock Co 2866DAT Chrome Receiver Pin Lock

Product Description

The MASTER LOCK CO 2866DAT is a chrome-plated steel bent receiver pin with an integrated swiveling lock head. Designed for trailer hitch applications, it secures a hitch receiver by passing through the receiver tube and locking in place. The swiveling lock head allows the key cylinder to rotate out of the way, making insertion and removal easier in confined or tight spaces. The lock is finished in chrome-plated steel for corrosion resistance and includes an all-weather cover that shields the key way from rain, dirt, and debris. Licensed HVAC and automotive service professionals, fleet maintenance technicians, and experienced DIYers install this hardware as a receiver security solution.

This receiver pin lock is suited for trailer hitches, equipment carriers, and bike racks that use standard 5/8 inch or 1/2 inch receiver holes. The bent pin design fits both pin sizes, making it a versatile option for shops that service mixed fleets or multiple hitch receiver configurations. It is appropriate for residential and light commercial towing setups where weather exposure is a routine concern. Key blanks compatible with this lock include Master Lock blank K1BOX and Ilco blank M1 TV 320-952, which simplifies key duplication for fleet use.
