Extruded grommeting-roll form, protects and insulates wires and cables from chafing against sharp chassis edges. The serrated design is particularly suited to irregularly shaped panel holes. Depending on the chassis thickness, grommeting may grip tightly by itself. If not, a touch of epoxy will keep it in place. Roll grommeting is the most cost effective way to protect wire and cables from sharp edges. Sold by the foot.
