Abb 233 Outlet Box 4 Inch Square 1 Inch Knockout

Product Description

The ABB 233 is a 4-inch square outlet box designed for use in commercial and residential electrical rough-in applications. It features 1-inch knockouts that accept standard conduit fittings and connectors. This box is a core component in branch circuit wiring, used to house wiring connections, devices, and fixture mounting points. Licensed electricians install this box during rough-in framing stages before drywall or ceiling finish. Each unit ships as a 2-pack, making it practical for multi-outlet and multi-circuit installations.

This outlet box is suited for wall and ceiling installations in both new construction and renovation work. It is used in residential, light commercial, and industrial electrical systems where a 4-inch square form factor is required. The 1-inch knockout configuration is compatible with common rigid metal conduit, EMT, and flexible conduit fittings used in standard branch circuit wiring. Electricians working under NEC guidelines will find this box appropriate for device, junction, and fixture applications requiring a square box footprint.
