Abb Installation Products BH234R 2-gang Old Work Electrical Box

Product Description

The ABB INSTALLATION PRODUCTS BH234R is a 2-gang old-work electrical box designed for retrofit and remodel installations where the wall surface is already finished. Built from rigid thermoset material, this box resists flexing and holds its shape under the stress of device installation and everyday use. With a 34 cubic inch capacity, it accommodates wiring for duplex receptacles, switches, and similar devices. Eight integrated cable clamps secure incoming conductors, and two mounting tabs anchor the box firmly to the drywall or plaster surface without requiring access to wall studs. Electricians and experienced remodel contractors are the primary installers.

This box is suited for residential and light commercial remodel work where new-construction boxes are not an option. It is installed directly through a cutout in an existing finished wall, making it appropriate for adding new outlets or switches in drywall, plaster, or similar wall assemblies. The 34 CUIN interior gives adequate room for single or multi-conductor cable runs typical of 15-amp and 20-amp branch circuits. The integrated cable clamps eliminate the need for separate snap-in clamps during rough-in.

Key Features

• 34 cubic inch interior capacity supports standard branch-circuit wiring volumes
• Rigid thermoset construction resists flexing and maintains box geometry after installation
• Eight integrated cable clamps secure NM, AC, or MC cable entries without separate hardware
• Two mounting tabs lock the box against the interior wall surface after insertion through cutout
• Old-work design requires no stud access, compatible with finished drywall and plaster walls
• 2-gang configuration supports side-by-side duplex devices, switches, or combination plates

Compatibility

Designed as an OEM-style old-work replacement and new-installation box for 2-gang device configurations in residential and light commercial retrofit wiring applications.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for box fill calculations and cable securing. De-energize the branch circuit at the panel and verify absence of voltage before pulling or connecting conductors. Trace and mark the wall cutout carefully before cutting to ensure the mounting tabs have adequate drywall thickness to grip. Do not overtighten the mounting tab screws, as excessive torque can crack the thermoset body.
