This damper was the solution to my problem on a oil furmance. Glad that I purchased this damper.

The gauge on the tee is 24, which is thinner than the nice 22 gauge pipe that is sold separately. The damper itself is a Field instruments brand, and is pretty nice unit. Seams to have quality construction, and no sharp edges.
Product is well made and very easy to assemble. Even this DIY can't screw it up.
