Description
Extension ring for 4 In. Square Box, 1-1/2 in. Deep, 21 Cu. In., with Concentric, 1/2 & 3/4 in., and 1/2 in. KO (50-Pack)
Features
- This extension ring provides a critical 21.0 cubic inch boost to your existing electrical enclosure, effectively doubling the available space for complex wiring configurations. By adding 1-1/2" of depth, it allows for the safe installation of larger smart dimmers, GFCIs, or multiple conductors without the risk of wire compression or insulation damage that can lead to short circuits.
- Featuring a versatile array of dual-sized concentric knockouts, this ring offers seamless transition points for both 1/2" and 3/4" EMT or flexible conduit. This flexibility eliminates the need for specialized adapters during a retrofit, allowing contractors and facility managers to quickly bridge power from an existing wall box to new surface-mounted runs in industrial or commercial environments.
- Fabricated from high-grade pre-galvanized steel, this extension ring is engineered to withstand the mechanical stresses of high-traffic commercial zones and industrial warehouses. The zinc coating provides superior corrosion resistance, ensuring the structural integrity of your grounding path and protecting your internal connections from moisture and environmental wear for decades.
- Specifically designed to mount onto any standard 4-inch square (4S) junction box, this ring features slotted mounting holes that compensate for box misalignment during installation. This "universal" fit ensures a tight, flush seal against the base box, maintaining UL-listed enclosure integrity and ensuring your surface-mounted electrical additions pass rigorous building inspections.
