Commonly installed in industrial facilities, commercial buildings, power distribution systems, manufacturing plants, and utility installations, this aluminum three-piece coupling provides a secure, rigid, and vibration-resistant conduit connection. Maintenance teams and electrical contractors use this fitting for repair, retrofit, expansion, and replacement of threaded conduit systems. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"672\" data-end=\"689\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"691\" data-end=\"1324\"\u003eThe Thomas \u0026amp; Betts 677AL is designed for joining 1-inch threaded rigid metal conduit and IMC in locations where rotating either conduit is impractical. Its ERICKSON® three-piece design allows conduit runs to be assembled or disassembled without disturbing the entire raceway. The copper-free aluminum construction offers excellent corrosion resistance while maintaining dependable electrical bonding, making it suitable for commercial, industrial, utility, and outdoor electrical installations. The coupling is concrete-tight and designed to resist vibration while maintaining conduit alignment. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1326\" data-end=\"1355\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1357\" data-end=\"2338\"\u003e• Manufacturer Part Number (MPN): 677AL\u003cbr data-start=\"1396\" data-end=\"1399\"\u003e• Brand: Thomas \u0026amp; Betts (ABB) – ERICKSON®\u003cbr data-start=\"1440\" data-end=\"1443\"\u003e• Product Type: Threaded Conduit Coupling\u003cbr data-start=\"1484\" data-end=\"1487\"\u003e• Trade Size: 1 in.\u003cbr data-start=\"1506\" data-end=\"1509\"\u003e• Conduit Type: Rigid Metal Conduit (RMC) and Intermediate Metal Conduit (IMC)\u003cbr data-start=\"1587\" data-end=\"1590\"\u003e• Coupling Style: Three-Piece ERICKSON® Coupling\u003cbr data-start=\"1638\" data-end=\"1641\"\u003e• Material: Copper-Free Aluminum\u003cbr data-start=\"1673\" data-end=\"1676\"\u003e• Finish: Natural Aluminum\u003cbr data-start=\"1702\" data-end=\"1705\"\u003e• Thread Type: NPS Threaded\u003cbr data-start=\"1732\" data-end=\"1735\"\u003e• Installation: Threaded\u003cbr data-start=\"1759\" data-end=\"1762\"\u003e• Construction: Concrete-Tight\u003cbr data-start=\"1792\" data-end=\"1795\"\u003e• Overall Length: 1-5\/8 in.\u003cbr data-start=\"1822\" data-end=\"1825\"\u003e• Outside Diameter: 1-29\/32 in.\u003cbr data-start=\"1856\" data-end=\"1859\"\u003e• Application: Joining threaded conduit where neither conduit can be rotated\u003cbr data-start=\"1935\" data-end=\"1938\"\u003e• Standards: UL 514B, UL File E23018, CSA Certified, NEMA FB1, ANSI C80.4\u003cbr data-start=\"2011\" data-end=\"2014\"\u003e• Compliance: RoHS 3 Compliant, REACH Compliant, TSCA Section 6(h) Compliant\u003cbr data-start=\"2090\" data-end=\"2093\"\u003e• Features: Three-piece design, corrosion-resistant aluminum construction, free-fitting threads for easy assembly, vibration-resistant connection, rigid in-line coupling, and dependable grounding continuity. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2340\" data-end=\"2364\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2366\" data-end=\"2436\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Thomas \u0026amp; Betts 676AL\u003cbr data-start=\"2388\" data-end=\"2391\"\u003e• Thomas \u0026amp; Betts 678AL\u003cbr data-start=\"2413\" data-end=\"2416\"\u003e• Thomas \u0026amp; Betts 677\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"mt-3 w-full empty:hidden\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv data-conversation-screenshot-content=\"\" class=\"[--thread-content-max-width:40rem] @w-lg\/main:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Thomas","offers":[{"title":"New","offer_id":51714002485550,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5d8df897-8e20-451c-a695-ad8cc3686c86.jpg?v=1770413455","url":"https:\/\/plgautomation.com\/products\/thomas-betts-677al-threaded-conduit-coupling","provider":"PLG Automation ","version":"1.0","type":"link"}
