Southwire 54171-S-UPC 4 Inch Old Work Octagon Box

Product Description

The SOUTHWIRE 54171-S-UPC is a 4-inch old-work octagon electrical box designed for installing ceiling and wall lighting fixtures, ceiling fans, and convenience outlets in existing construction. Built from durable steel, this box is suited for retrofit installations where the wall or ceiling surface is already closed in. It ships with combo-head fixture mounting screws included. Electricians turn to this style of box when adding or relocating a light or fan outlet without opening large sections of drywall.

This old-work octagon box is used in residential and light commercial retrofit electrical projects. It is appropriate for ceiling-mounted applications such as light fixtures, pendant lights, ceiling fans, and surface-mounted devices. Because it is designed for old-work installation, it fits into existing finished ceilings and walls without requiring access from above or behind the surface.

Installation Notes
