Rok Hardware 5 Pack Round Grommet 3 (76mm) Diameter Made of ABS Black

These grommets are made from hard plastic to help prevent cracking and wear from pulling cables and wires through. With the movable top you can close off the hole when not in use. These are eyelets that are used to strengthen or protect an opening or to insulate and protect an object passing through an opening. The cover plate can also be removed completely to allow cables with electric plugs attached to pass through. They protect cables from abrasion by giving them a smooth surface to rub against and direct them where they need to go through their openings. The perfect way to keep your work surface clean and tidy is by organizing cables and wires through your desk work table tabletop or other furniture.
