The box arrives preset at 0.5 inches and adjusts in or out by turning a single screw, allowing the installer to bring the face flush with any wall covering without cutting or shimming. It carries a 21 cubic inch capacity, which accommodates standard device wiring loads. The patented bracket clips directly onto a stud, and the included mounting clip keeps the assembly secure throughout the adjustment process. UL Listed for safety compliance. Licensed electricians and skilled tradespeople typically install this box during new construction or remodel work.\u003c\/p\u003e\n\u003cp\u003eThis adjustable box is well suited for residential and light commercial rough-in applications where finished wall thickness is not known at the time of box installation. Common scenarios include drywall installations where thickness varies between 0.375 inches and thicker fire-rated assemblies. The preset depth and tool-driven adjustment eliminate the need to stock multiple fixed-depth boxes for a single job, reducing material waste and install time on multi-room projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable depth via single screw — no additional tools needed to set flush position\u003c\/li\u003e\n  \u003cli\u003ePreset at 0.5 inches from the factory for standard drywall rough-in\u003c\/li\u003e\n  \u003cli\u003e21 cubic inch capacity supports standard single-gang device wiring\u003c\/li\u003e\n  \u003cli\u003eIncluded bracket clips onto any stud for fast, stable mounting\u003c\/li\u003e\n  \u003cli\u003ePatented design accommodates varying wall covering thicknesses\u003c\/li\u003e\n  \u003cli\u003eUL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction single-gang adjustable electrical box for use with standard single-gang devices in residential and light commercial wall assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician in accordance with applicable NEC requirements.
