Description
4 In. Square Box, 1-1/2 in. Deep, 21 Cu. In., with Raised Ground Screw, with Concentric, 1/2 & 3/4 in. KO (50-Pack)
Features
- This 4-inch square outlet box features a standard 1-1/2 inch depth, providing a 21.0 cubic inch capacity. It is the industry-standard choice for basic branch circuit applications, offering sufficient room for a single duplex receptacle or switch and associated conductors while maintaining a slim profile for shallow wall cavities.
- The 52171K is equipped with Hubbell’s "K" style concentric knockouts (1/2" and 3/4"), providing maximum field flexibility. These knockouts are precision-stamped to stay secure during transport but break away cleanly when struck, allowing for a tight, professional fit for EMT or Rigid conduit without the need for additional reaming
- Fabricated from 0.0625" pre-galvanized steel, this box is built to resist corrosion and physical impact. The heavy-duty metallic construction provides a reliable, low-impedance ground path, ensuring long-term electrical safety and structural stability in schools, hospitals, and commercial office buildings.
- Designed for high-productivity environments, this box features standardized mounting holes and a "sides and bottom" knockout arrangement. Whether you are surface-mounting on masonry or installing in a metal-stud wall with a bracket, the rigid steel frame prevents twisting, ensuring your devices sit flush and secure every time.
- This Hubbell-Raco box is UL Listed and compliant with all NEC requirements for metallic outlet boxes. Its precision-engineered flat edges ensure a tight, code-compliant seal when paired with mud rings or covers, maintaining the fire-shield integrity of the wall or ceiling assembly in the event of an internal electrical fault.
