Value Collection 47008860 Galvanized Duct Top Ceiling Box

Product Description

The VALUE COLLECTION 47008860 is a galvanized steel duct top ceiling box designed for connecting round duct to ceiling diffusers or registers in residential and light commercial HVAC duct systems. With a 6-inch inside diameter opening and an 8-inch by 8-inch footprint, this box transitions from round supply duct to a square ceiling boot configuration. The galvanized steel construction provides corrosion resistance suitable for typical air distribution environments. HVAC installers and sheet metal contractors use this fitting as a standard supply-air terminal connection at the ceiling plane.

This ceiling box is used at supply-air termination points where a 6-inch round duct connects to an 8-inch by 8-inch ceiling opening. Typical applications include residential forced-air systems, light commercial rooftop unit distribution, and new-construction duct rough-ins. The fitting sits flush against the ceiling deck, allowing a register or diffuser grille to mount directly over the face opening. It is suited for horizontal ceiling installations where a square face register is the intended terminal device.

Key Features

• 6-inch inside diameter round duct connection for standard supply branch runs
• 8-inch by 8-inch square face matches common ceiling register cutout sizes
• 7.75-inch overall height accommodates typical ceiling joist cavity depth
• Galvanized steel construction resists corrosion in conditioned-air applications
• Standard gauge sheet metal fabrication for consistent fitment and rigidity

Compatibility

Designed as an OEM-style replacement or new-construction fitting for residential and light commercial forced-air duct systems using 6-inch round supply branch ducts terminating at an 8-inch by 8-inch ceiling opening.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors following local mechanical codes and SMACNA duct construction standards. Power down the air handling equipment before connecting or sealing duct sections. Secure the ceiling box to framing with appropriate fasteners and seal all seams with mastic or listed duct tape per local code requirements. Do not overtighten sheet metal screws at the duct collar, as this can distort the round opening and affect airflow.
