The grommet is a part to protect a cable being fed through a hole opened in a cabinet (cable protection). If a grommet is not used, the cable sheath is damaged due to vibrations or another impact and a short circuit may be caused in the worst case, resulting in a fire. The filmed grommet has the function of concealing the hole before leading a cable through the hole and the function of protecting the cabinet inside from dust. A cap to cover the hole is also available.
