Closed Rubber Grommets

Manufactured from durable TPE and PVC materials, these closed grommets offer reliable flexibility and long-term performance across a wide range of industrial and electrical applications. The closed centre design allows quick, tool-free installation with no adhesives required, ensuring a tight, permanent fit once installed. Commonly used in control panels, switch boxes, machinery housings and electronic enclosures, these blanking grommets are supplied in a range of sizes to suit standard panel cut-outs, with UK-held stock available for fast supply.
