Brady's yellow compact keyed-different safety padlock has a one inch aluminum shackle and non-conductive, spark resistant lock body. This lightweight padlock offers superior corrosion and chemical resistance. The unique key cylinder prevents electricity from traveling from the shackle to the key, protecting workers when the key is inserted. This safety padlock comes with one padlock, but is available in packages of six and a variety of different colors, including black, blue, brown, green, orange, purple, red and white.
