RACO 153 4 in. Drawn Steel Octagon Box, 1-1/2 in. Deep, AC/MC/Flex Clamps

The RACO 153 is a 4 in. drawn steel octagon box built for dependable junction and outlet box applications in residential and commercial electrical systems. This drawn steel enclosure measures 1-1/2 in. deep and includes three 1/2 in. knockouts along with built-in AC/MC/Flex clamps, allowing electricians to terminate Armored Cable, Metal Clad, and Flex wiring systems directly into the box without additional connectors. Designed for use without a mounting bracket, the RACO 153 is suited for applications where the box is secured directly to framing or an existing structure. Backed by UL Listing, this octagon box delivers the code-compliant performance electrical professionals expect from RACO.

Key Features

• Trade Size: 4 in. octagon configuration provides a standard, widely compatible footprint for ceiling fixtures, outlet devices, and junction points.
• Durable Drawn Steel Construction: The box is drawn from steel rather than welded, resulting in a one-piece, seamless enclosure that resists deformation and provides consistent strength at every wiring point.
• Box Depth: At 1-1/2 in. deep, the interior offers adequate volume for splicing conductors, mounting devices, and accommodating wiring systems without overcrowding.
• Triple Knockouts: Three 1/2 in. KO's give installers multiple, clearly marked entry points for conduit or cable, simplifying layout planning on the job site.
• Integrated AC/MC/Flex Clamps: Built-in clamps are engineered for Armored Cable, Metal Clad, and Flex wiring systems, securing cable directly at the knockout and reducing the need for separate cable connectors.
• No-Bracket Design: Supplied without a mounting bracket, this box configuration is intended for installations where the box is fastened directly using separately installed mounting hardware.
