Overview

The ABB 531511/2-G PVC Coated Gray Pre-Galvanized Steel Square Box Extension Ring (SKU: 531511/2-G) is a precision-engineered electrical accessory designed to expand the capacity of existing 4-inch square electrical boxes in commercial and industrial installations. Constructed from durable pre-galvanized steel with a protective PVC coating, this extension ring delivers superior corrosion resistance and long-term reliability in demanding environments. The 4-inch square profile and 1.5-inch depth provide an additional 21 cubic inches of internal volume, enabling electricians to accommodate additional wiring, devices, or conduit connections without replacing the original electrical box. Key features include strategically placed 1/2-inch knockouts for flexible conduit entry and exit, ensuring compatibility with standard 1/2-inch conduit systems. The drawn steel construction guarantees dimensional accuracy and structural integrity, preventing deformation during installation or use. The gray PVC coating not only enhances corrosion resistance but also provides an additional layer of insulation and protection against moisture, chemicals, and physical damage. This extension ring is ideal for retrofitting existing installations, expanding device capacity in control panels, or adapting electrical boxes for new wiring configurations. Compatible with all standard 4-inch square electrical boxes, the ABB 531511/2-G is manufactured in the USA and meets industry standards for electrical enclosures.
