It mounts at the end of electrical metallic tubing to protect wire and cable insulation from abrasion at conduit terminations. Without a bushing at the conduit end, sharp metal edges can damage conductor insulation and create potential fault or fire hazards. The CAP400 provides a smooth, insulating throat that meets NEC requirements for protecting conductors at conduit openings. Electricians install this fitting during rough-in and trim-out on conduit runs in commercial and residential applications.\u003c\/p\u003e\n\u003cp\u003eThe CAP400 is suited for use on 4-inch EMT conduit terminations in panel enclosures, junction boxes, and equipment knockouts. It is a common fitting on commercial electrical projects where large-diameter EMT runs terminate at switchgear, distribution panels, and motor control centers. Its lightweight HDPE construction makes handling on the job site straightforward and does not add meaningful weight to the conduit assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch trade size fits standard 4-inch EMT conduit ends\u003c\/li\u003e\n  \u003cli\u003eHigh-density polyethylene (HDPE) construction resists impact and electrical tracking\u003c\/li\u003e\n  \u003cli\u003eSmooth insulating throat protects conductor insulation from conduit edge abrasion\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.14 pounds for easy handling during installation\u003c\/li\u003e\n  \u003cli\u003eOne-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insulating bushing for standard 4-inch EMT conduit terminations in commercial and residential electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed electrician should install this fitting in accordance with the National Electrical Code (NEC). De-energize the circuit and verify absence of voltage before working in any enclosure where this bushing will be installed. The bushing seats by hand at the end of the EMT conduit before or after the locknut is secured, depending on the fitting configuration. Do not force the bushing onto conduit ends that are burred or deformed — ream the conduit end first to ensure a clean, flush seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Density Polyethylene (HDPE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: One Year Limited\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Canada\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: SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CAP400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51346254070066,"sku":"CAP400","price":32.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552328.png?v=1782075293","url":"https:\/\/voomisupply.com\/products\/southwire-cap400-4-inch-emt-insulating-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
