Southwire 54171-R-UPC Old Work 4 Inch Steel Octagon Box

Product Description

The SOUTHWIRE 54171-R-UPC is a steel old-work octagon box designed for installing ceiling and wall lighting fixtures, paddle fans, and convenience outlets in retrofit applications. Built from durable steel with a combo-head fixture mount and cover mounting screws included, this box is suited for electricians working in existing finished walls and ceilings where a new-work box is not practical. The old-work design allows installation without direct access to framing, making it a standard choice for fixture replacements and lighting upgrades in residential settings.

This octagon box is used in residential electrical rough-in and finish work where ceiling or wall-mounted lighting fixtures, fans, or outlet devices need a secure, code-compliant mounting point. It is appropriate for retrofit scenarios in finished drywall ceilings and walls. Electricians installing replacement fixtures or adding new lighting drops in existing construction will find this box fits standard octagon cover plates and fixture canopies.
