Southwire 54151-J-UPC Bracket Mount 4x4 Octagon Box

Product Description

The SOUTHWIRE 54151-J-UPC is a bracket-mount octagon box designed for installing ceiling and wall lighting fixtures, fans, convenience outlets, and related devices. Built from durable steel, this 4-inch by 4-inch box provides a solid, code-compatible mounting point for light fixtures and electrical devices in standard residential and light commercial applications. It ships with combo-head fixture cover mounting screws included, reducing the need for additional hardware on the job. Electricians rely on this style of box as a foundational rough-in component wherever a ceiling or wall-mounted electrical device needs a secure, flush-mount enclosure.

This octagon box is suited for ceiling and wall rough-in work in residential new construction and renovation projects. It is appropriate for use with standard lighting fixtures, paddle fans, and convenience outlet assemblies. The bracket-mount configuration allows for installation between framing members, making it a practical choice in both new framing and retrofit scenarios where stud or joist access is available.

Key Features

• Steel construction provides durability and meets standard code requirements for metallic electrical enclosures
• 4-inch by 4-inch octagon form factor fits standard lighting fixture canopies and covers
• Bracket-mount design supports installation between framing members without direct fastening to a stud or joist face
• Compatible with ceiling and wall lighting fixtures, paddle fans, and convenience outlet devices
• Includes combo-head fixture cover mounting screws for complete installation readiness

Compatibility

Designed as an OEM-style replacement and standard rough-in solution for residential and light commercial octagon-box applications requiring a 4-inch by 4-inch metallic enclosure.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit at the breaker panel and verify absence of voltage with a meter before beginning any wiring work. Ensure the bracket is secured firmly to framing members so the box does not shift under the weight of the attached fixture or fan. Do not exceed the fixture weight rating for the box and bracket assembly as marked or specified by the authority having jurisdiction.
