Imperial Mfg Group Usa Inc GV0627-C Register Boot 4x12 to 6

Product Description

The IMPERIAL MFG GROUP USA INC GV0627-C is a 90-degree galvanized steel register boot designed for residential and light commercial HVAC duct systems. It transitions from a 4-inch by 12-inch rectangular duct opening to a 6-inch round collar, allowing supply air to be directed through a floor, wall, or ceiling register. Fabricated from 30-gauge galvanized steel, this boot provides a rigid, corrosion-resistant connection point between the branch duct and the register grille. HVAC installers and sheet metal contractors use this fitting during new construction and retrofit duct work where a rectangular-to-round transition is needed at the register termination point.

This register boot is suited for residential forced-air heating and cooling systems where supply ducts terminate at floor or wall registers. The 90-degree angle directs airflow perpendicular to the duct run, which is the standard orientation for most floor-mounted and sidewall register installations. It is packaged in quantities of 6 units per package, making it a practical stock item for contractors running multiple supply runs on a single job.

Key Features

• Rectangular-to-round transition: 4 inches by 12 inches inlet to 6-inch round collar
• 90-degree boot configuration for floor, sidewall, and ceiling register terminations
• 30-gauge galvanized steel construction for corrosion resistance and structural rigidity
• Standard fitment for supply-side register terminations in forced-air duct systems
• Sold in packages of 6 units for contractor convenience

Compatibility

Designed as an OEM-style replacement and new-construction fitting for residential and light commercial forced-air HVAC supply duct systems requiring a 4-inch by 12-inch rectangular to 6-inch round register boot termination.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut down the air handling system and lock out power before cutting into existing duct work or securing the boot to a branch duct. Secure the boot to the duct with sheet metal screws and seal all joints with UL 181-listed mastic or foil tape per local mechanical code requirements. Do not compress or restrict the 6-inch collar opening, as this will reduce airflow and affect system balance.
