Bridgeport Fittings 163-G Mighty-Bond Zinc Grounding Locknut with Aluminum Lug
The Bridgeport Fittings 163-G Mighty-Bond zinc grounding locknut with aluminum lug is designed to create a secure, low-resistance bonding connection between rigid, IMC, or EMT conduit and a metal enclosure, panel, or box. This locknut series is available in trade sizes ranging from 1" to 4", so installers can size the fitting to match the conduit and enclosure or panel knockout on the job. Every size in the 163-G Mighty-Bond family features a solid zinc body paired with an integrated aluminum grounding lug that accepts a bonding jumper, giving installers a single fitting that both secures the conduit and establishes an equipment grounding path. The Mighty-Bond design eliminates the need for a separate grounding bushing or clamp on many installations, saving labor time in panel and enclosure terminations. This locknut is built for electricians and contractors who need a dependable grounding connection on commercial, industrial, and institutional projects, whether the run is a compact 1" conduit drop or a larger 4" service entrance.
Key Features
- Trade Size Range: Available from 1" up to 4" to fit standard conduit and matching enclosure or panel knockouts across a wide range of installations.
- Durable Zinc Construction: A solid zinc body provides strength and corrosion resistance for long-term reliability in the field across every size in the series.
- Integrated Aluminum Grounding Lug: A built-in aluminum lug accepts a bonding jumper directly at the locknut, keeping the grounding connection compact and secure regardless of conduit size.

- Grounding Locknut Function: Bonds conduit to enclosures, panels, and boxes to help maintain a continuous, code-focused equipment grounding path.
- Threaded Locknut Body: Threads onto conduit to secure the raceway to the enclosure while the aluminum lug provides the bonding point, sized appropriately for each trade size offered.
