Master Flow 10×6 to 6 in Universal Register Box w/ Flange, 30-Gauge Steel HVAC
The Master Flow 10 in. x 6 in. to 6 in. Universal Register Box with Flange is a durable 30-gauge galvanized steel HVAC register box designed to create a straight, in-line transition from 6 in. round pipe or insulated flexible duct to a 10 in. x 6 in. air register or grille. The built-in flange allows installation before drywall and provides a secure mounting surface for register screws, sheetrock framing, or joist attachment for a cleaner, more stable install. Suitable for all HVAC types, this register box is built for reliable performance in demanding conditions and is rated for temperatures up to 390°F; seal all seams with code-approved sealant or HVAC tape (not included) for best results.
