4-11/16" × 4-11/16" Square Steel Electrical Box
Description
The 4-11/16" × 4-11/16" Square Steel Electrical Box is designed for electrical conduit installations requiring larger wiring capacity and multiple conduit entries. Manufactured from high-quality pre-galvanized steel, this square box provides strong mechanical protection and secure enclosure for wire splicing, device mounting, and distribution connections.
With its expanded internal space compared to standard 4" × 4" boxes, it is widely used in commercial and industrial electrical systems where higher conductor fill capacity is required. Suitable for EMT conduit installations and heavy-duty applications.
