Product Description

The ORBIT INDUSTRIES 3RB-50-FB is a drawn steel switch box designed for standard electrical wiring installations in both residential and commercial applications. Constructed from 16-gauge sheet steel, this box measures 3.5 inches wide with a 1.5-inch depth, providing a compact and durable housing for wiring connections. The unit includes a flat bar bracket for secure mounting and features pre-formed knockouts for convenient conduit or cable entry. Licensed electricians and electrical contractors typically install this box as part of new construction or retrofit wiring work.

The 3RB-50-FB is suited for residential and commercial wiring installations where a drawn octagon-style switch box with bracket mounting is required. The box includes three 0.5-inch knockouts on the sides and one 0.5-inch knockout on the bottom, offering flexible routing options for conduit or cable entry. Its 16-gauge steel construction provides the structural rigidity required for standard in-wall or surface-mounted electrical rough-in work.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify the absence of voltage before beginning work. Ensure the box is secured firmly to the mounting surface using the included bracket before pulling wire through the knockouts.
