CABAC split-style Nylon snap bushing is designed to protect cables from rough, raw edges on panel holes. As the name suggests, snap bushing features self contained teeth that snap in place to provide a secure fit. Once installed, the grommet creates a smooth surface that prevents the cable from being cut or chafed.. Split bushing has several advantages over regular fixed bushing. The split allows the grommet to be fitted to a range of panel hole sizes, so precision is not as critical. Additionally, the split design makes it possible for the bushing to be retrofitted to cords or wires that are already in place.
