Constructed from 16-gauge sheet steel, it measures 4 inches by 4 inches by 1.5 inches deep, providing a sturdy enclosure for wiring connections and device mounting. The box includes multiple knockout configurations: two 0.5-inch knockouts and two MKO (multiple knockout) cutouts on the sides, plus three 0.5-inch and two 0.75-inch knockouts on the bottom. Licensed electricians install this box during rough-in wiring to house switches, receptacles, or wire splices behind finished wall and ceiling surfaces.\u003c\/p\u003e\n\u003cp\u003eThe 4RB-MKO suits both residential new construction and commercial retrofit wiring projects. Its welded construction provides a rigid enclosure that holds up to the demands of daily trade use. The MKO side knockouts allow flexible conduit entry sizing, making it practical for installations where conduit diameter requirements may vary. This box is appropriate for use in standard stud-framed walls and ceiling assemblies where a square 4-inch electrical box is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16-gauge sheet steel construction for rigid, durable enclosure\u003c\/li\u003e\n  \u003cli\u003eWelded box design maintains structural integrity under load\u003c\/li\u003e\n  \u003cli\u003eSide knockouts: two 0.5-inch and two MKO cutouts for flexible conduit entry\u003c\/li\u003e\n  \u003cli\u003eBottom knockouts: three 0.5-inch and two 0.75-inch for multiple conduit configurations\u003c\/li\u003e\n  \u003cli\u003e4 x 4 x 1.5-inch interior dimensions suit standard square-box device plates and covers\u003c\/li\u003e\n  \u003cli\u003eSuitable for both residential and commercial wiring applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation electrical box compatible with standard 4-inch square box covers, mud rings, and device plates used in residential and commercial electrical rough-in work.\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.
