The ABB INSTALLATION PRODUCTS B117RSWR is a single-gang shallow old work flanged electrical box designed for retrofit installations in existing walls. With a 17 cubic inch capacity and a depth of 2 inches, it provides additional wiring room without requiring access from behind the wall. The flanged design secures the box against the drywall face during installation. Electricians use this box when adding or relocating receptacles, switches, or low-voltage devices in finished residential or light commercial spaces where wall cavities have limited depth.
This box is suited for retrofit electrical work in residential and light commercial construction. It is engineered to work with 1 inch by 2 inch stud construction and is a practical solution when standard-depth boxes cannot be used due to shallow wall conditions. The 17 CUIN volume accommodates standard wiring configurations for receptacles and switches in single-gang applications. Electricians and qualified installers use this box when finishing basement spaces, remodeling existing rooms, or adding circuits without opening walls.
Designed as an OEM-style replacement and retrofit solution for single-gang old work electrical box applications in residential and light commercial finished wall installations.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits at the panel before cutting the wall opening or pulling wire. Use a stud finder to confirm wall cavity depth and framing conditions before cutting. Ensure all conductors are properly secured and box fill calculations comply with NEC Article 314.
