Orbit Industries 4SB-50-FB Switch Box 4x4x1.5 in Flush Galvanized

Product Description

The ORBIT INDUSTRIES 4SB-50-FB is a galvanized steel switch box designed for flush-mount electrical installations in residential and commercial wiring applications. Fabricated from 16-gauge sheet steel with a galvanized finish, this 4 inches x 4 inches x 1-1/2 inches box provides a durable enclosure for device mounting and wire management. It ships with nine 1/2-inch knockouts on the sides and five 1/2-inch knockouts on the bottom, giving installers flexible conduit entry options. The included flush bracket supports secure, flush-wall positioning during rough-in and finish work.

This switch box is suited for both new-construction and retrofit wiring projects in residential and light commercial settings. The 4-inch square format and 1-1/2-inch depth accommodate standard wiring devices and provide adequate wire fill for single or multi-conductor runs. Electricians use this box in wall assemblies where a flush surface-mounted profile is required, typically in conjunction with a plaster ring or mud ring cover.

Installation Notes

Installation of electrical boxes must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit at the panel and verify with a non-contact voltage tester before beginning work. Secure the box firmly to framing or structural backing before pulling wire, and ensure knockout entries are properly bushed or fitted with appropriate connectors to protect cable sheathing.
