Abb Installation Products BH118R Single Gang Old Work Box

Product Description

The ABB INSTALLATION PRODUCTS BH118R is a single-gang, old-work electrical box designed for retrofit installations in existing walls. Constructed from rigid thermoset plastic, the box resists flexing and holds its shape under load, maintaining a secure fit once mounted. With an 18 cubic inch capacity, it meets NEC fill requirements for standard device and wiring configurations. The BH118R features four built-in cable clamps and two mounting tabs, giving electricians secure cable management and a stable mount without additional hardware. This box ships in a package quantity of 36 units per case.

The BH118R is suited for residential and light commercial retrofit wiring projects where new-construction boxes are not practical. It is installed in existing drywall or plaster walls without access to wall studs, using the integrated mounting tabs to clamp against the wall surface from inside the opening. Electricians use it when adding outlets, switches, or low-voltage devices to finished walls. The Super Blue color aids visibility during rough-in and inspection.

Key Features

• 18 cubic inch interior capacity supports standard fill requirements for outlets and switches

Compatibility

Designed as an OEM-style old-work single-gang box for use with standard residential and light commercial switch and outlet devices in retrofit electrical installations.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for box fill and cable securing. De-energize the circuit at the panel before cutting the wall opening or pulling cables. Use the integrated mounting tabs to secure the box against the interior wall surface after inserting through the cutout. Do not overtighten the mounting tab screws, as the thermoset body can crack if forced beyond the design stop.
