Description
Extension ring for 4 In. Square Box, 2-1/8 in. Deep, 30 Cu. In., with Concentric, 1/2 & 3/4 in., and 1/2 in. KO (40-Pack)
Features
- Adding an expansive 30.0 cubic inches of internal volume, this 2-1/8-inch deep extension ring provides critical breathing room for complex multi-conductor runs. It allows commercial electricians to seamlessly add new circuits, large GFCI receptacles, or bulky smart switches to an existing junction box without risking illegal, dangerous wire crowding or code violations
- Designed with a standard 4" x 4" layout, this extension ring sits flush on top of any standard 4-inch square metallic box. This precise mechanical alignment eliminates structural layout guesswork during wall or ceiling retrofits, allowing contractors to extend the electrical box forward to match newly added drywall, tile, or plaster layers.
- Outfitted with an array of precision-punched 1/2-inch and 3/4-inch concentric knockouts, this ring offers total entry flexibility from multiple sides. These clean-breaking ports enable rapid connection of armored cables (BX) or EMT conduit, giving technicians a simple way to expand facility wiring branches without tearing out the underlying infrastructure.
- Manufactured from high-strength pre-galvanized steel, this metallic extension ring provides a continuous, highly reliable ground path and maximum fire protection. The drawn-steel design ensures the walls will not warp, twist, or bend under mechanical tension, making it an excellent upgrade over flimsy plastic extenders in demanding job site environments.
