Flexible rubber grommets can provide a compliant interface at cable openings. Some products have slotted membranes for routing; others use an open passage or a split profile.
Choose the construction from the product drawing. Match the mounting dimensions and panel thickness, and allow room for the cable bundle and connectors. Follow the cables' permitted bend requirements when routing them in different directions.
A grommet is one part of cable organization and does not replace support or strain relief. Select the compound and appearance for the application, then check seating and clearance after installation.
