Orbit Industries 4RB-NM Steel Octagon Switch Box 4x4x1.5 in

Product Description

The ORBIT INDUSTRIES 4RB-NM is a steel octagon switch box designed for nonmetallic (NM) cable installations in residential and commercial electrical wiring. Constructed from 16-gauge sheet steel, this welded box measures 4 inches x 4 inches x 1.5 inches deep, providing a sturdy and code-compliant enclosure for device or junction applications. The box ships ready for installation with pre-configured knockout arrangements on the sides and bottom, reducing field prep time. Licensed electricians rely on this type of box for secure, grounded enclosures in standard stud-framed walls and ceilings.

This switch box is suited for residential new construction and commercial light-gauge framing where NM cable is the primary wiring method. It accommodates standard device installations and junction needs at 4-inch octagon mounting patterns. The knockout layout includes two 0.5-inch side knockouts, four loom-style side knockouts, and one 0.5-inch bottom knockout, giving installers flexible cable entry options for a variety of rough-in scenarios.
