Switch/Outlet Box, 3-Gang, Depth: 3-1/2", Nail-On, Non-Metallic

Carlon SuperBlue® Boxes combine the features of the hard shell thermoset box and the thermoplastic PVC style box to create a “new” rigid non-metallic wiring box. Molded out of specially formulated thermoplastic material, Carlon SuperBlue® boxes are so strong they won't crack or break in extreme environments. So rigid, they resist flexing and hold their shape even in the worst applications. The boxes are designed to nest inside each other to take up less space on the shelf or in the truck, while still providing the largest wirefill capacity in their class.
