The die cast zinc body provides a durable, corrosion-resistant housing, while the tin plated aluminum grounding lug accepts copper or aluminum conductors from 14 AWG through 1\/0 AWG. A zinc plated steel set screw locks the bushing in any desired position on the conduit thread, and a zinc plated steel clamping screw secures the conductor in the lug. The insulated throat protects wire insulation during pull-through, and the low-friction surface reduces abrasion on cable jackets. Licensed electricians install this fitting as part of equipment grounding continuity in metallic conduit systems.\u003c\/p\u003e\n\u003cp\u003eThe GBL-400 is used with a locknut to bond rigid metal conduit or IMC conduit at a panel, junction box, or enclosure entry point. At 1-1\/4 inch trade size, it fits standard threaded rigid and IMC conduit in residential and commercial installations where an insulated grounding bushing with an integral bonding lug is required by code. The insulated throat design makes it suitable for service entrance and feeder conduit terminations where conductor insulation protection is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInsulated throat protects wire insulation during conduit termination and pull-through\u003c\/li\u003e\n  \u003cli\u003eTin plated aluminum grounding lug accepts 14 AWG to 1\/0 AWG copper or aluminum conductors\u003c\/li\u003e\n  \u003cli\u003eZinc plated steel set screw locks bushing at any position on the conduit thread\u003c\/li\u003e\n  \u003cli\u003eDie cast zinc body construction for strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eLow surface friction design reduces cable insulation abrasion during wire pulls\u003c\/li\u003e\n  \u003cli\u003eRated to 150 degrees C; listed to UL 467 and CSA C22.2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 1-1\/4 inch trade size rigid metal conduit and IMC conduit.

De-energize all circuits and verify zero voltage at the panel or enclosure before beginning conduit termination work. Thread the bushing onto the conduit end and seat it against the locknut; tighten the set screw to secure position. Torque the clamping screw to secure the bonding conductor in the lug per the conductor manufacturer and applicable NEC requirements for equipment grounding connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Threaded, Set Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Type\u003c\/strong\u003e: Insulated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size Range\u003c\/strong\u003e: 14 to 1\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLug Type\u003c\/strong\u003e: Tin Plated Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Material Compatibility\u003c\/strong\u003e: Copper\/Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Die Cast Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Screw and Clamping Screw Material\u003c\/strong\u003e: Zinc Plated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1.89 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.61 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 150 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Rigid Conduit \/ IMC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL 467, CSA C22.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: NEMA FB-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: IN\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: APPLETON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GBL-400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APPLETON","offers":[{"title":"Default Title","offer_id":51284071547186,"sku":"GBL-400","price":30.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279435.jpg?v=1781067806","url":"https:\/\/voomisupply.com\/products\/appleton-gbl-400-conduit-grounding-bushing-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
