Hoffman strain relief fittings can be installed quickly because they are easy to handle. The washer has gripping fingers to make sure there is even pressure around the grommet. The grommet itself is notched so it stays in position and the body has a groove for the O-Ring. These fittings can be used for many different applications both indoors and outdoors, including control cabinets, instrumentation, food processing, sensors, wind turbines and solar panels.
