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

Product Description

The SOUTHWIRE 54151-JR-UPC is a bracket-mount steel octagon box designed for installing ceiling and wall lighting fixtures, ceiling fans, and convenience outlets. Built from durable steel, it provides a solid, code-ready mounting point in residential and light commercial electrical rough-in work. The box ships with combo-head fixture mounting screws included, reducing the need for additional hardware at the rough-in stage. Licensed electricians rely on this type of box as the foundation for fixture and fan installations where a secure, flush-mounted enclosure is required by NEC guidelines.

This octagon box is suited for new construction and retrofit ceiling or wall fixture installations. It is appropriate for residential applications such as bedroom and hallway light fixture rough-ins, as well as light commercial projects requiring a standard 4 inch x 4 inch octagon enclosure. The bracket-mount design accommodates installation between framing members, making it a practical choice where direct stud or joist attachment is not available.

Key Features

• Steel construction for durable, long-lasting performance in ceiling and wall applications
• Bracket-mount design allows installation between framing members without direct stud attachment
• Compatible with ceiling fans, light fixtures, and convenience outlets
• Combo-head fixture mounting screws included
• Standard 4 inch x 4 inch octagon footprint for common fixture compatibility

Compatibility

Designed as an OEM-style replacement and new-install octagon box for standard residential and light commercial ceiling and wall lighting fixture, ceiling fan, and convenience outlet applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify the absence of voltage with a meter before beginning work. The bracket-mount design requires proper adjustment and securing of the bracket to framing members before pulling conductors into the box. Do not exceed the box fill capacity as calculated per NEC Article 314.
