Abb 153 Round Outlet Box 4 Inch with Bx Knockout

Product Description

The ABB 153 is a 4-inch round outlet box designed for use with BX (armored cable) wiring installations. This metal outlet box provides a secure, code-compliant enclosure for electrical connections at ceiling or wall junction points. The BX-ready knockout design accommodates standard armored cable connectors, making termination straightforward for licensed electricians working on residential or light commercial wiring projects. The round form factor is the standard choice for ceiling-mounted fixture support and branch-circuit junction applications where a square or rectangular box is not required.

This outlet box is suited for new construction and retrofit electrical work where armored cable is the specified wiring method. Electricians use this box type at ceiling fixture locations, junction points, and device rough-in locations that call for a 4-inch round enclosure. It ships 25 units per carton, making it practical for contractors stocking up for multi-unit or production work.

Key Features

• 4-inch round profile fits standard ceiling and wall rough-in applications

Compatibility

Designed as an OEM-style replacement and standard rough-in box for residential and light commercial electrical installations requiring a 4-inch round enclosure with BX cable entry.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit at the panel and verify absence of voltage before making any connections inside the box. Secure the box firmly to framing or a rated brace before pulling cable, and ensure all knockouts are properly fitted with listed connectors rated for the cable type used.
