Non-sparking set-up wedges contain no ferrous metals, so they resist creating sparks. This reduces the risk of ignition when setting up parts in environments where combustible dust or flammable liquids, gas, or vapors are present. Set-up wedges position or add space between parts and materials. They spread apart pipe flanges and other mated parts to slide in a gasket, set up work pieces on planers and milling machines, level machinery, and act as a fulcrum for pry bars. These wedges can stack to create the necessary height or separation.
