The EzyFit® damper has a compact folded design which allows you to slip the damper through the register. It works well in applications where the ductwork is buried behind drywall.
After installation, a magnet holds it firmly in place. EzyFit connects to the control panel with plenum-rated tubing that you run inside the ductwork.
Applications include any round metal ductwork that you can reach through a register or another access point. Not suitable for non-metallic ductwork or rectangular ducts.
