Gromstrip is a continuous length, extruded U-channel grommet that is used as a protective covering over sharp edges for added protection of wire and cable bundles. Gromstrip is easy to install into any hole, regardless of configuration — simply cut to the desired length and press into place. Minimal panel space is required for Gromstrip to snugly grip the surface and will protect any wires passing through against fraying, cutting, or abrasion.
