Grounding Bushing · 2-1/2 in Trade Size · Insulated Threaded Lug Type · Bridgeport Fittings GB212
SKU: GB212
Insulated grounding bushing for 2-1/2 in rigid or IMC conduit, used to bond threaded raceway to an enclosure with a lug connection. Commonly selected where a bonding conductor termination is required at the raceway entry; actual code requirements depend on the installation method and local electrical code.
What this product is for
This grounding bushing is used on 2-1/2 in trade size threaded rigid metal conduit or IMC to provide conductor protection at the raceway end and a lug point for bonding to the enclosure or grounding system. It is typically used in commercial, industrial, and service raceway terminations.
Use for
- 2-1/2 in trade size rigid metal conduit or IMC
- Bonding threaded conduit to cabinets, pull boxes, gutters, and enclosures
- Installations requiring an insulated throat and grounding lug connection
- Service entries, distribution equipment, and industrial raceway terminations
Avoid for
- EMT where a threaded grounding bushing is not the correct fitting type
- Non-threaded raceway connections
- Applications where a split grounding bushing is specifically needed for retrofit or post-pull installation
Best for
Electricians and maintenance teams needing a standard insulated grounding bushing for large threaded conduit entries. This style is best when the bushing can be installed during conduit assembly and a lugged bonding point is required at the enclosure.
Installed in
Commercial buildings, industrial facilities, OEM panels, service equipment, switchgear-related raceway entries, and large junction or pull boxes. For a 2-1/2 in trade size fitting, the nominal conduit size is approximately 2.5 in (63.5 mm).
Why this product exists
Large threaded metal raceways may need both edge protection for conductors and a reliable external bonding point. An insulated grounding bushing combines those functions in one fitting, helping simplify termination at the enclosure.
Compared with similar products
Compared with a standard insulating bushing, this product adds a grounding lug for bonding. Compared with split grounding bushings, this threaded one-piece style is typically chosen for new work where the fitting can be installed before conductors are pulled. Split styles are commonly used for retrofit work or where conductors are already in place.
Typical buying guidance: choose the trade size to match the conduit, then confirm the lug wire range and fitting style required by the job. Actual suitability depends on conductor size, enclosure bonding method, and local electrical code.

Note: Live search results strongly indicate the legacy row is misbranded as Hubbell. The SKU GB212 appears to be an internal or legacy code, while current market listings for Bridgeport 2-1/2 in insulated grounding bushings commonly map to part numbers such as 387 or 387-DC. Manual review is recommended before final publish.
