Value Collection IBNRG-5-BKN Rubber Grommet 50 Pack

Product Description

The VALUE COLLECTION IBNRG-5-BKN is a Buna-N rubber grommet designed to protect wiring, tubing, and cables where they pass through metal panels, enclosures, and bulkheads. Measuring 11/16 inches in outside diameter and 9/32 inches in overall thickness, this grommet seats into a 1/2-inch slot diameter opening with a 1/16-inch slot width. The inside diameter is 3/8 inches, providing a snug fit around standard-gauge wire bundles and conduit. Molded from Buna-N rubber with a Shore A hardness of 45-55, it resists oils, fuels, and moderate temperature extremes common in mechanical and electrical installations. Electricians, HVAC technicians, and panel fabricators use this grommet to eliminate sharp-edge contact that can cut through wire insulation over time.

This grommet is suited for use in electrical panels, HVAC equipment cabinets, control enclosures, junction boxes, and light commercial or residential mechanical rooms wherever conductors or tubing penetrate sheet metal. Its black color blends with standard panel finishes. The slot-style opening allows the grommet to be installed over existing wiring without fully threading the wire through, making it practical for retrofit and service work. Each package contains 50 grommets, supporting both new-construction installations and service stock replenishment.

Key Features

• 11/16-inch OD fits a 1/2-inch slot diameter panel opening
• 50-piece package supports installation and service inventory needs

Compatibility

Designed as an OEM-style replacement or standard-stock grommet for electrical panels, control enclosures, and mechanical equipment cabinets requiring a 1/2-inch slot diameter opening with a 1/16-inch slot width.

Installation Notes

De-energize all circuits and lock out power to the panel or enclosure before installing or replacing grommets. The slot design allows the grommet to snap over conductors already in place; ensure the grommet seats fully and evenly around the panel opening to maintain edge protection. Electricians should verify the inside diameter accommodates the wire bundle or conduit outside diameter before installation. Follow applicable NEC requirements for conductor protection at panel knockouts and enclosure penetrations.
