Special mount to fit trailer hitch receivers. These are hand made here locally and are of the finest quality materials and workmanship. We start with a new trailer hitch and a new Firestick Stainless Steel Bracket. The top of the bracket is cut off and it is welded to the top of the trailer mount. Now the hole is a perfect 1/2 inch for standard stud mounts AND the bottom is a stainless surface where the stud mount ground hits. Paint where the hitch goes in the receiver is ground off for good ground connection. The rest is painted black.
