Overview

The ABB 52171-OW 4-inch square old work electrical box is a rugged, pre-galvanized steel enclosure designed for retrofit and renovation applications requiring conduit integration. Engineered with welded construction for superior structural integrity, this box delivers 30.3 cubic inches of internal volume within a 4-inch square x 2-1/8-inch deep footprint. The pre-galvanized steel construction ensures corrosion resistance in industrial, commercial, and residential environments, while the integrated old work ears enable secure mounting in existing finished walls without requiring structural modifications. Key features include dual 1/2-inch and 3/4-inch knockouts for flexible conduit entry, accommodating standard trade sizes for seamless integration with electrical systems. The welded seams eliminate weak points common in stamped or spot-welded alternatives, providing long-term durability under vibration and mechanical stress. Ideal for electricians and contractors retrofitting electrical systems in offices, retail spaces, or light industrial facilities, this box supports single-device installations or serves as a junction point for branch circuits. Its compatibility with 1/2-inch and 3/4-inch conduits (trade sizes) ensures broad applicability across residential, commercial, and light industrial projects. The absence of internal obstructions simplifies wire pulling and termination, reducing installation time and labor costs.
