Constructed from malleable iron with a zinc plating, this connector delivers corrosion resistance and mechanical strength in demanding installation environments. The insulated throat protects wire insulation from abrasion at the point of entry. This fitting is installed by licensed electricians on commercial and residential wiring projects where liquid-tight conduit systems are required to maintain moisture and dust exclusion at box terminations.\u003c\/p\u003e\u003cp\u003eThis connector is suited for use in wet, damp, and industrial locations where liquid-tight flexible conduit is routed into metallic enclosures, panel boxes, or conduit bodies. Typical applications include mechanical rooms, HVAC equipment connections, pump installations, and outdoor electrical equipment where code requires a sealed conduit termination. The straight body style is used where conduit enters the box at a direct angle without requiring a bend at the fitting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStraight body profile for direct conduit-to-box entry\u003c\/li\u003e\n\u003cli\u003eMalleable iron construction with zinc plating for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInsulated throat protects conductor insulation from abrasion\u003c\/li\u003e\n\u003cli\u003eLiquid-tight design maintains moisture and dust exclusion at the termination point\u003c\/li\u003e\n\u003cli\u003eZinc plated finish suitable for use in damp and wet location applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for use with standard liquid-tight flexible metal conduit systems in residential and commercial electrical installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with NEC requirements for liquid-tight conduit fittings. De-energize all circuits before beginning work on any enclosure or conduit system. Ensure the locknut is tightened securely against the enclosure wall to maintain the liquid-tight seal and proper ground continuity. Do not overtighten to the point of cracking the malleable body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron, Zinc Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Style\u003c\/strong\u003e: Straight, Insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 14.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.55 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: China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MSTR-50-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51346390712626,"sku":"MSTR-50-B","price":19.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552327.png?v=1782078958","url":"https:\/\/voomisupply.com\/products\/southwire-mstr-50-b-liquid-tight-straight-box-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
