Open Rubber Grommets
Open rubber grommets are snap in inserts that fit into a panel hole to protect cables and wires from sharp edges. These open grommets help reduce rubbing and vibration damage where a cable passes through metal enclosures and sheet panels. The grommet holes are open centre, this lets you push cables straight through without feeding connectors, making open rubber grommets useful for new installs and maintenance. For the best fit, always check the correct grommet dimensions including panel hole size, panel thickness and cable diameter. Our range covers mounting hole sizes from 5mm up to 63.5mm to suit a wide variety of applications.
Our open grommets provide a practical solution for protecting cable entry points in electrical panels, machinery and industrial equipment. Each rubber grommet features a central opening for cable routing, helping to prevent damage caused by contact with sharp panel edges. For alternative styles and designs, explore our complete range of rubber grommets, including closed and sealing options for different installation requirements.

Choosing the Right Open Rubber Grommet
When selecting open rubber grommets, check the mounting hole diameter, panel thickness and cable diameter to ensure the correct fit. The open centre should accommodate the cable whilst the outer groove holds the rubber grommet securely within the panel opening. Choosing the correct dimensions helps reduce cable movement, prevent abrasion and maintain a neat installation.
