Overview

The ABB Octagon Box Extension Ring, SKU 551511/2-25, is engineered for electrical installations requiring additional depth and capacity. Constructed from durable, pre-galvanized steel with a drawn construction, this extension ring offers superior corrosion resistance and longevity, making it suitable for industrial, commercial, and residential applications. It features a 4-inch diameter and a 1-1/2-inch depth, providing a substantial internal volume of 15.8 cubic inches. This increased capacity is ideal for accommodating larger wiring configurations, splices, or additional electrical components. The ring is equipped with 1/2-inch knockouts, facilitating straightforward conduit entry and connection. Designed to seamlessly integrate with standard 4-inch octagon boxes, this extension ring ensures a precise fit and secure mounting. The pre-galvanized finish protects against rust and wear, ensuring reliable performance even in demanding environments. ABB Installation Products are known for their quality and durability, and this extension ring is no exception, offering a dependable solution for expanding the volume of existing electrical boxes. Its robust construction and thoughtful design make it an essential component for electricians and contractors seeking to meet project specifications for wiring space and accessibility. The drawn construction method ensures consistent wall thickness and dimensional accuracy, contributing to ease of installation and a professional finish. This extension ring is manufactured in the US, adhering to high production standards. It is an excellent choice when the existing octagon box does not provide sufficient space for new wiring or device installations, offering a practical and cost-effective method to increase box volume without replacing the entire fixture. The 1/2-inch knockouts are strategically placed for versatile conduit routing. The 15.8 cubic inch volume is a key specification for ensuring code compliance and ease of maintenance in electrical systems.
