Abb 3210 Thermoplastic Knockout Bushing Rigid Imc

Product Description

The ABB 3210 is a one-piece, non-metallic knockout bushing made from thermoplastic material. It is designed to protect wire insulation at the point where conduit enters an enclosure, panel, or junction box through a knockout opening. The 3210 fits a 0.875-inch knockout and is rated for use with rigid metal conduit and IMC conduit systems. Electricians install this bushing to eliminate sharp metal edges that can damage conductor insulation during pull-through, keeping installations compliant with NEC requirements for conductor protection at conduit terminations.

This bushing is used in residential and commercial electrical installations wherever rigid or IMC conduit terminates at an enclosure knockout. It is a common component in panel installations, junction box terminations, and equipment connections. The one-piece thermoplastic construction makes installation straightforward and eliminates the corrosion concerns associated with metallic alternatives in wet or corrosive environments.

Key Features

• One-piece construction for simple, single-step installation
• Non-metallic thermoplastic material resists corrosion
• Fits 0.875-inch knockout openings
• Compatible with rigid metal conduit and IMC conduit
• Protects conductor insulation from sharp knockout edges

Compatibility

Designed for use with rigid metal conduit and IMC conduit at 0.875-inch knockout openings in electrical enclosures and junction boxes.

Installation Notes

A licensed electrician should de-energize the panel or enclosure before beginning conduit termination work. The bushing snaps or seats into the knockout opening before or after the conduit is positioned, depending on site conditions. Installation must comply with applicable NEC requirements for conductor protection at conduit entries. Inspect the bushing seating to confirm full contact around the knockout edge before pulling conductors.
