Dayton 2C520 16-Inch Wall Backdraft Damper – Vertical Mount, Galvanized Steel

Got a powerful exhaust fan but dealing with backdrafts and bugs getting in?

You need the Dayton 2C520.

This is a heavy-duty, vertical mount wall backdraft damper designed to fit fans with a 16-inch diameter.

The frame is made from tough 20-gauge galvanized steel, and it's built to last.

It measures 19 inches high and wide with a 6-inch depth.

It's made right here in the US and comes with a 1-year warranty.

When your fan turns off, these shutters close tight to keep outside air out.

It's a simple, mechanical solution for better ventilation control in your shop, warehouse, or industrial space.

Just match it to your rough opening and you're good to go.
