The part fits a 4-inch trade-size conduit with 4\" - 8 NPS threads and features an insulated throat to isolate the grounding path from the conduit, making it suitable for electrical distribution and service applications where a defined ground connection is required through threaded conduit. For the 4-inch model, exterior dimensions include A = 5-1\/8 in, B (Hex) = 4-15\/16 in, C = 3-3\/4 in, and D = 1-1\/16 in, reflecting a robust machined-steel body. The bushing is constructed from steel and, in this AMFICO family, is listed with zinc plating to resist corrosion in standard installations. \u003c\/p\u003e\u003c\/div\u003e","brand":"AMF","offers":[{"title":"New","offer_id":51659932401966,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b9e9e7fa-4519-4ae3-b3ac-547fefc39ab9.jpg?v=1769530927","url":"https:\/\/plgautomation.com\/products\/industrial-rcb400b-ground-bushing-4-inch-zinc-plated-steel","provider":"PLG Automation ","version":"1.0","type":"link"}
