Constructed from ASTM A47-77 32510 malleable iron with a zinc electroplated dichromate epoxy powder coat finish, this mounting hood provides a durable, corrosion-resistant connection point between the outlet box and the luminaire. It ships complete with a connection block, mounting plate, and gasket. Listed under UL 844, UL 1598, and UL 1598A, the obv1 meets the classification requirements for Class I Division 2 Groups A, B, C, and D; Class II Division 1 and 2 Groups E, F, and G; and Class III enclosures. Electricians and lighting contractors working in wet or classified hazardous locations specify this hood when mounting Mercmaster series fixtures to cast or standard outlet boxes.\u003c\/p\u003e\n\u003cp\u003eThe obv1 is intended for ceiling-mount applications in wet locations and NEC-classified hazardous environments. It is specifically used on Mercmaster Jr HID luminaires and the V51 Series incandescent lighting fixture from Appleton. Typical installations include industrial facilities, petrochemical plants, food processing areas, wastewater treatment sites, and other locations requiring listed wet-location or hazardous-location luminaire mounting hardware. The included gasket and mounting plate ensure a sealed, code-compliant assembly at the box interface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction per ASTM A47-77 32510 for impact resistance in industrial environments\u003c\/li\u003e\n  \u003cli\u003eZinc electroplated dichromate epoxy powder coat finish for corrosion resistance in wet locations\u003c\/li\u003e\n  \u003cli\u003eListed to UL 844, UL 1598, and UL 1598A for hazardous and wet location use\u003c\/li\u003e\n  \u003cli\u003eRated Class I Division 2 Groups A, B, C, D and Class II Division 1 and 2 Groups E, F, G, and Class III\u003c\/li\u003e\n  \u003cli\u003eIncludes connection block, mounting plate, and gasket for complete ceiling box assembly\u003c\/li\u003e\n  \u003cli\u003eCeiling mount configuration compatible with cast and standard outlet box types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on the Appleton Mercmaster Jr HID luminaire and the V51 Series incandescent lighting fixture.

De-energize the circuit and verify the absence of voltage before beginning any work on the outlet box or luminaire. Ensure the mounting surface and outlet box are rated for the enclosure class required by the installation location. Verify the gasket is properly seated before final assembly to maintain the wet-location and hazardous-location integrity of the connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron (ASTM A47-77 32510)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Electroplated Dichromate Epoxy Powder Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Ceiling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Type\u003c\/strong\u003e: Cast \/ Outlet Box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHazardous Location Rating\u003c\/strong\u003e: Class I Div 2 Groups A, B, C, D; Class II Div 1 and 2 Groups E, F, G; Class III\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Wet Location\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListings\u003c\/strong\u003e: UL 844, UL 1598, UL 1598A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Connection Block, Mounting Plate, Gasket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78138163960\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: obv1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APPLETON","offers":[{"title":"Default Title","offer_id":51268823810354,"sku":"OBV1","price":996.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912776.jpg?v=1780706796","url":"https:\/\/voomisupply.com\/products\/appleton-obv1-ceiling-box-mounting-hood-mercmaster","provider":"Voomi Supply","version":"1.0","type":"link"}
