The box ships preset at 0.5 inches depth and adjusts continuously from flush to 1.75 inches of wall thickness after the box is already mounted. With a 21-cubic-inch interior capacity, it provides adequate volume for standard receptacle and switch devices. Electricians install it by clipping the included bracket directly onto the stud, then turning the adjustment screw to bring the box face flush with any finished wall surface. The UL Listed rating confirms third-party safety compliance.\u003c\/p\u003e\n\u003cp\u003eThis box is suited for single-gang device installations in residential and light commercial framing. It is especially useful in remodel situations where drywall, tile backer, or paneling may differ in thickness from room to room or from the original framing plan. The screw-drive adjustment mechanism eliminates the need to remove and reposition the box after the wall covering is applied, reducing callbacks and rework. Licensed electricians and experienced installers working under NEC guidelines will find this box straightforward to position correctly on the first pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable depth from 0 to 1.75 inches to accommodate varying wall covering thicknesses\u003c\/li\u003e\n  \u003cli\u003eShips preset at 0.5 inches for standard drywall installations\u003c\/li\u003e\n  \u003cli\u003e21 cubic inch interior capacity meets NEC fill requirements for typical single-gang device installations\u003c\/li\u003e\n  \u003cli\u003eClip-on bracket mounts directly to stud without additional fasteners\u003c\/li\u003e\n  \u003cli\u003eScrew-drive mechanism adjusts box position in or out after wall covering is installed\u003c\/li\u003e\n  \u003cli\u003eUL Listed for safety compliance in residential and commercial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation option for single-gang electrical box applications requiring adjustable depth in standard wood or metal stud framing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician in accordance with the National Electrical Code (NEC).
