It accepts 1\/2 inch and 3\/4 inch knockouts to accommodate standard conduit entries. A built-in spring steel clip secures the box firmly against the wall surface as mounting screws are tightened, eliminating the need for additional fasteners into the block. The box provides 42.3 cubic inches of interior volume and supports both 4x4 single-gang and two-gang device screw hole patterns. Licensed electricians install this box when adding or upgrading wiring devices in existing masonry construction.\u003c\/p\u003e\n\u003cp\u003eThe FSCB44 is suited for retrofit electrical rough-in work in residential and light commercial concrete block construction. Typical applications include adding receptacles, switches, or low-voltage devices to existing CMU walls without cutting back to a stud or using anchor bolts. The spring clip design speeds installation in finished or occupied spaces where access is limited to the face of the wall.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpring steel clip locks box securely against concrete block wall as screws are tightened\u003c\/li\u003e\n  \u003cli\u003eAccepts 1\/2 inch and 3\/4 inch knockouts for standard conduit entries\u003c\/li\u003e\n  \u003cli\u003e42.3 cubic inch interior volume meets NEC fill capacity requirements for most device configurations\u003c\/li\u003e\n  \u003cli\u003eScrew hole pattern compatible with 4x4 single-gang and two-gang devices\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in masonry environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style retrofit electrical box for use with standard 4x4 and two-gang wiring devices in concrete block masonry walls.\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. De-energize the circuit at the panel and verify absence of voltage before beginning work.
