Orbit Industries FSDB-NBH Fan Support Box 4x4 Steel

Product Description

The ORBIT INDUSTRIES FSDB-NBH is a new construction fan support box designed for residential and commercial electrical wiring installations. Fabricated from 16-gauge sheet steel, this 4-inch by 4-inch by 2-1/8-inch box provides a rigid, code-ready mounting point for ceiling fans and light fixtures in new-frame construction. Three 1/2-inch knockouts and two loom knockouts are pre-formed into the housing, giving electricians the entry options needed for standard wiring runs without field modification. The adjustable bar hanger spans 16 inches to 24 inches, allowing single-person installation across standard and non-standard joist spacing without additional hardware.

This fan support box is suited for new construction framing where joists or ceiling structure is accessible before drywall. It is installed by licensed electricians during the rough-in phase of residential and light commercial projects. The adjustable hanger bar seats between joists and locks at the desired span, positioning the box flush for finish work. Typical applications include ceiling fan rough-in, light fixture mounting, and switch box placement in wood-frame construction.
