The box measures 4 inches square with a depth of 2.125 inches, providing ample interior volume for device wiring and splices. It ships with both 1\/2-inch and 3\/4-inch knockouts (KO), giving installers flexibility when routing conduit or cable. The welded construction delivers rigid, code-ready mounting in new-work framing installations where a bracket-mounted deep box is required.\u003c\/p\u003e\u003cp\u003eThis box is suited for standard electrical rough-in work in wood-frame walls and ceilings. The FB (flat bar) bracket allows the box to be secured directly to framing members, making it a common choice on commercial tenant improvement jobs, residential new construction, and light industrial work. The dual KO sizes support a range of conduit types and trade sizes, reducing the need for additional fittings or adapters on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 inches square profile matches standard 4S device ring and cover compatibility\u003c\/li\u003e\n\u003cli\u003e2.125-inch depth provides increased wire capacity for multi-conductor applications\u003c\/li\u003e\n\u003cli\u003eWelded steel construction for structural rigidity in permanent installations\u003c\/li\u003e\n\u003cli\u003eIncludes both 1\/2-inch and 3\/4-inch knockouts for flexible conduit entry\u003c\/li\u003e\n\u003cli\u003eFB bracket design for direct attachment to wood or metal framing members\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard rough-in fitting compatible with 4-inch square electrical box covers, mud rings, and device rings used in commercial and residential electrical systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes.
