New Work Ceiling Box, 4" Square, 1-5/8" Deep, captive nail and molded bracket mounting, Switch and Outlet Box with Wire Clamps.

  • SKU: B118
  • The 4" square design provides larger cubic-inch capacity than standard device boxes, allowing more conductors and easier splicing. The nonmetallic construction eliminates grounding requirements, resists corrosion, and reduces installation weight, while built-in mounting brackets or nails allow fast, secure installation during rough-in. Integrated cable clamps or knockouts further simplify NM cable entry, helping reduce installation time and labor costs.
  • 4" square new-work plastic boxes are installed during new construction before drywall is applied and are typically nailed or screwed directly to wall studs or framing members. They are used to house branch-circuit wiring splices, switches, receptacles, or fixture connections, and often serve as junction boxes where additional wiring capacity is required in residential and light commercial installations.
