Orbit Industries FS4PB-NBH Fan Support Switch Box 4 in

Product Description

The ORBIT INDUSTRIES FS4PB-NBH is a new construction fan support switch box designed for use in residential and commercial electrical wiring installations. Constructed from 16-gauge sheet steel, this box measures 4 inches in diameter and 1/2 inch deep, with an adjustable fan support bar that spans 16 to 24 inches to fit standard joist spacing. The NBH designation indicates a no-bracket-hole configuration. Licensed electricians install this box to support ceiling fans and light fixtures in new-construction framing, where the support bar is secured directly between ceiling joists before drywall is applied.

This switch box is suited for new construction applications where ceiling joists are accessible prior to drywall installation. The adjustable bar accommodates 16-inch to 24-inch joist spacing, making it compatible with standard residential and light commercial framing layouts. It is typically installed during the rough-in phase of electrical work, before ceiling surfaces are closed. The 1/2-inch box depth is appropriate for switch wiring and fan canopy connections in finished ceiling assemblies.

Installation Notes
