The Rota-Reel 200-20R-ST and 700-50R-ST static-grounding reels are now available from Hunter Spring Products, a unit of Ametek. The entire exterior of the reels (housing, cable, end clamps, and hardware) is made from 304 stainless steel. Static-grounding reels are used extensively in the petroleum industry, where they are often mounted on refueling vehicles and on platforms at fueling stations. They are also used in industry to ground large pieces of equipment, such as conveyor belts, mixing machines, and dust-collection equipment, especially where there may be a potential risk of explosion caused by static electricity. 304 stainless steel offers extensive corrosion resistance, and, as a low-sparking material, it is widely accepted for use in hazardous (explosive) environments. These reels are designed to convey static electricity to an earth/ground source safely without producing a spark. The grounding cable is stored on a spool inside the reel’s housing. The cable is pulled from the housing to a desired length and clamped to an earth/ground source. An internal ratchet mechanism keeps the cable fixed at the desired length. A light tug releases the ratchet and allows the cable to rewind onto the spool.
