🌱 A ventilation ducting tool designed to fit different-sized duct hole openings together, connecting smaller ducting to bigger fans and vice versa. Using this duct adapter to connect your ventilation fans to your ducting will help retain your system’s CFM efficiency. It features a raised lip on the reducer end to provide extra grip on ducting or duct openings, while the increaser end features a flat brim to achieve a flush fit. The galvanized steel body is finished with a zinc coating that aids in its resistance to corrosion and high temperatures.
