Description
Extension ring for 4 In. Octagon Box, 1-1/2 in. Deep, 15 Cu. In., with Concentric, 1/2 & 3/4 in. KO (50-Pack)
Features
- Specifically engineered to mount onto standard 4-inch octagon steel boxes, this extension ring provides a seamless fit for increasing internal wire volume. It is an essential solution for renovation projects where you need to add more conductors or larger devices to an existing ceiling or wall box without the destructive process of tearing out the original housing.
- This ring adds a critical 1-1/2 inches of depth to your electrical enclosure, significantly increasing the cubic-inch capacity of the box. This extra space solves the common problem of "box fill" violations, providing the necessary room to safely tuck away wires and connectors without risking pinched insulation or heat buildup behind light fixtures or sensors.
- Featuring a specialized K-bar bracket assembly, this extension ring allows for secure attachment to joists or studs, providing a rock-solid foundation for heavy ceiling fans or chandeliers. The integrated bar hanger simplifies the alignment process, ensuring your fixture remains centered and stable even in challenging overhead installations or "old work" retrofit scenarios.
- Manufactured from high-grade galvanized steel, this extension ring is built to resist corrosion and structural warping over decades of service. Its rigid metallic design ensures a reliable ground path and superior mechanical protection for your electrical connections, meeting the strict UL standards required for both commercial and residential building inspections.
- Equipped with multiple 1/2-inch and 3/4-inch side knockouts, the H55151KBAR provides maximum flexibility for running EMT or flexible conduit from various angles. These precision-stamped knockouts are easy to remove, allowing electricians to quickly adapt the box to complex wiring layouts while maintaining a professional, code-compliant finish.
