Value Collection C87339 Expandable Nylon Grommet 50 Pack

Product Description

The VALUE COLLECTION C87339 is an expandable nylon grommet designed to protect wiring, tubing, and cable runs passing through panel cutouts, sheet metal enclosures, and structural panels. The grommet features a 3/4 inch outside diameter, a 1/2 inch inside diameter, and a 25/64 inch overall thickness. Constructed from nylon, it flexes to snap into a standard panel hole and grips the edge to prevent abrasion on conductors and hoses. Electricians, HVAC technicians, and panel fabricators install these grommets during rough-in and assembly work where a clean, code-conscious wire entry is required. Each package contains 50 grommets.

These expandable grommets are suited for residential and light commercial applications where wiring or tubing must pass through metal or plastic panels without direct contact with the hole edge. Common install scenarios include electrical enclosures, HVAC equipment cabinets, control panels, and equipment frames where consistent hole protection across multiple penetrations is needed. The expandable design allows a single grommet size to fit a range of hole tolerances, reducing the need to stock multiple sizes for similar panel gauges.

Key Features

• Expandable design snaps into panel cutouts without adhesive or fasteners
• Nylon construction resists abrasion and provides electrical insulation at wire entry points
• 3/4 inch outside diameter with 1/2 inch inside diameter for standard hole applications
• 25/64 inch overall thickness accommodates typical light-gauge panel stock
• Sold in a 50-piece package for production and service work efficiency

Compatibility

Designed as a standard expandable grommet replacement suitable for use in electrical enclosures, HVAC equipment panels, and general sheet metal fabrication applications requiring a 3/4 inch OD grommet with a 1/2 inch inside passage.

Installation Notes

Installation is performed by electricians, HVAC technicians, or panel fabricators and requires no special tools beyond a clean panel cutout sized to accept a 3/4 inch OD grommet. De-energize all circuits and confirm power is off before inserting grommets into live equipment panels. Press the grommet firmly into the cutout until the flange seats flush against the panel surface. Do not force cables through the grommet opening beyond the rated inside diameter, as overstretching can compromise the protective seal.
