Constructed from pre-galvanized steel at 1\/16 inch wall thickness, it provides a durable enclosure for wiring, switches, receptacles, and lighting fixtures. The box ships with 8-32 cover mounting screws pre-assembled, saving time on installation. At 21 cubic inches of interior capacity and 16 available knockouts for conduit entry, the 8189 gives electricians flexible routing options without requiring field modifications to the box body.\u003c\/p\u003e\n\u003cp\u003eThe RACO 8189 is suited for residential and light commercial ceiling applications where a square, flush-mount outlet box is required. Its conduit-entry configuration makes it a natural fit for EMT and rigid conduit systems in finished ceilings, junction points, and fixture rough-ins. The square 4-inch footprint aligns with standard mud rings and covers used in commercial electrical work, making it a common choice for electricians working under NEC guidelines for box fill and device mounting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21 cubic inch interior capacity supports multiple conductors and devices within NEC box fill limits\u003c\/li\u003e\n  \u003cli\u003e16 knockouts provide conduit entry flexibility for varied routing configurations\u003c\/li\u003e\n  \u003cli\u003ePre-galvanized 1\/16 inch steel construction for corrosion resistance in typical indoor ceiling environments\u003c\/li\u003e\n  \u003cli\u003e2-gang design accommodates side-by-side device or fixture mounting\u003c\/li\u003e\n  \u003cli\u003e8-32 cover mounting screws pre-assembled for faster installation\u003c\/li\u003e\n  \u003cli\u003eSquare shape compatible with standard 4-inch square covers and mud rings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ceiling outlet box compatible with standard 4-inch square covers, mud rings, and conduit fittings used in residential and commercial electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes.
