The ECM INDUSTRIES LLC GHG-1550 is a flexible black vinyl hole grommet sold in a 4-pack, designed to snap into punched or drilled holes in steel electrical boxes, panels, and sheet metal. The grommet protects electrical cables and wires from abrasion against raw metal edges. With a 1/2 inch inside diameter, an 11/16 inch required drill hole, and a 25/32 inch overall diameter, it fits standard knockout and punched openings commonly found in electrical enclosures. Electricians and panel technicians install these grommets during rough-in and finish wiring work to meet code requirements for cable protection at penetration points.
This grommet is suited for residential and light commercial electrical work where cables or wires pass through steel junction boxes, control panels, or sheet metal enclosures. It is a common consumable used during new construction, panel upgrades, and equipment wiring jobs. The flexible vinyl construction allows the grommet to snap firmly into place without tools, making installation fast during high-volume wiring tasks. Each package contains 4 individual grommets.
Designed as a snap-in replacement or new-installation grommet for steel electrical boxes, control panels, and sheet metal sheeting with 11/16 inch punched or drilled holes.
Installation is performed by licensed electricians or qualified electrical technicians. De-energize all circuits in the enclosure before beginning work, in accordance with NFPA 70 lockout/tagout requirements. Align the grommet with the prepared 11/16 inch hole and press firmly until the retaining lip snaps over the panel edge. Inspect the grommet seat to confirm full contact around the hole perimeter before routing cables through.
