Bridgeport Fittings 162-GI Mighty-Bond Insulated Grounding Locknut with Aluminum Lug, 3/4"

The Bridgeport Fittings 162-GI is a 3/4" Mighty-Bond insulated grounding locknut designed to deliver a dependable, low-resistance ground path for conduit and raceway systems in commercial and industrial electrical installations. Constructed with a durable zinc die-cast locknut body and an integrated aluminum lug, this fitting combines long-term corrosion resistance with a secure mechanical grounding connection that installers can count on. A ball-burnished, mirror-smooth, tin-plated finish further enhances surface conductivity while helping the locknut resist corrosion in demanding electrical environments. As part of the Bridgeport Fittings Mighty-Bond series, the 162-GI is engineered to insulate the conductor from the raceway while still maintaining a solid, code-compliant grounding path. Electricians and contractors rely on Bridgeport Fittings hardware for consistent, dependable grounding performance on every job.

Bridgeport Fittings 162-GI – Frequently Asked Questions

1) What trade sizes does the Bridgeport Fittings Mighty-Bond insulated grounding locknut come in?
Two trade sizes: 3/4 inch (part 162-GI) and 1 inch (part 163-GI). Order by the trade size of the conduit or the hub the locknut threads onto, not by the grounding conductor size.
2) What is a grounding locknut with a lug actually used for on a conduit run?
It replaces the ordinary locknut at a box, panel, or enclosure hub and adds a screw lug so a bonding jumper can be landed right at the connection. That gives you a mechanical ground path from the raceway to the equipment ground without drilling and tapping the enclosure or adding a separate grounding bushing. Bridgeport calls the line Mighty-Bond, and the 162-GI and 163-GI are the insulated grounding versions.
3) Will the aluminum lug on the 162-GI accept a copper grounding conductor?
The lug on the Mighty-Bond grounding locknut is aluminum. Aluminum-bodied lugs are commonly dual-rated, but the conductor range and any AL/CU rating are marked on the fitting and its carton, so read the lug marking on the part you receive before landing a copper jumper in it.
4) Is this locknut suitable for a damp or corrosive environment like a parking garage or plant floor?
The body is zinc die-cast and carries a ball-burnished, tin-plated finish, which is specified for corrosion resistance as well as surface conductivity. That combination is the usual choice for commercial and industrial conduit grounding, including panelboard, switchboard, and enclosure connections. For direct-buried or continuously wet locations, use a fitting listed for that condition.
5) What does the insulated part of an insulated grounding locknut do?
The insulated design isolates the conductor from the raceway edge at the entry while the lug keeps a continuous ground path to the enclosure. In plain terms, you get conductor protection at the knockout and the bonding point in one fitting rather than stacking a separate insulating bushing behind a plain locknut.
6) Can I use the 162-GI on EMT and rigid conduit, or only one of them?
It threads onto standard trade-size conduit hubs and fitting threads, so it works wherever a 3/4 inch threaded male hub or connector enters a box, which covers threaded rigid and IMC as well as the threaded end of an EMT connector. Match the fitting to the trade size, 3/4 inch for the 162-GI and 1 inch for the 163-GI.
7) I need to standardize grounding locknuts across a facility. Are the 3/4 inch and 1 inch the same design?
Yes, both are the same Mighty-Bond insulated grounding locknut design, zinc die-cast with a tin-plated finish and an integrated aluminum lug, differing only in trade size. Stocking 162-GI for 3/4 inch runs and 163-GI for 1 inch covers the two most common branch-circuit conduit sizes with one part family.
