The MK-2551A/U provides a safe path to discharge lightning, enhancing safety of personnel and equipment. It also helps

to control noise in signal circuits. The total resistance-to-ground ratio is equal to or better than that of a single ground rod,

allowing the equipment to better survive a lightning strike than a single ground rod. The kit consists of 15 galvanized steel stakes captive on 20 meters (65 feet) of galvanized wire rope on a reel. All 15 pegs must be driven into the earth. Each peg has a star cross section and is tapered from the top to the bottom. The complete kit weighs 25 pounds, and includes a 3-pound hammer, the 65-foot wire and two 10 foot jumper cables will adequately protect a 5-ton truck.
