High-capacity junction. Universal commercial standard.

Execute professional-grade circuitry with this 4-Inch Square Electrical Box, the industry-standard "1900 box" for commercial and residential junctions. Fabricated from robust 1.1mm galvanized steel, it offers superior crushing resistance and grounding continuity compared to plastic alternatives. Its deep 2-inch profile provides ample cubic volume for complex splices, wire nuts, and multiple conduit runs. Featuring versatile concentric 1/2" & 3/4" knockouts, this box adapts effortlessly to various conduit sizes, making it the go-to enclosure for surface-mounted exposed work or concealed device installations (requires mud ring).

Features
  • Commercial Standard: Known as a "1900 Box," this 4-inch square enclosure is the backbone of commercial electrical rough-ins for junctions and device mounting.
  • High Volume: The 2-inch depth allows for a higher wire fill capacity than standard 1-1/2" boxes, preventing overcrowding when splicing multiple circuits.
  • Versatile Knockouts: Equipped with concentric 1/2" and 3/4" knockouts on all sides, allowing for flexible conduit entry without the need for drilling or punches.
  • Multi-Purpose: Functions as a heavy-duty junction box for splicing wires or accepts a "Mud Ring" (Plaster Ring) to mount switches, outlets, or lighting fixtures.
  • Heavy-Gauge Steel: 1.1mm thick galvanized construction ensures a solid, crush-proof installation and excellent EMI shielding for sensitive electronics.
  • Grounding: Includes a raised ground bump or tapped hole for a secure 10/32 grounding screw connection.
