Review: Well built - Replaced a leaking damper this has help keep the room warmer and drafts out. Was easy to install and use.
Review: Great solution to broken/non-functional dampers - Out of the box and in use in about 15 minutes. The old damper in our firebox does not move freely, so this was the perfect solution. I used existing hardware in the fireplace to hook the cable when closed, so I cannot comment on installation of the bracket. If the damper is not closed tightly it will collect water that then drops down the chimney when it is opened. When closed tightly, the lid has a slight pitch, which should make the water run off the side. Quality material, sturdy and very sound. It fit perfectly, which was great because I just guessed at the size. I was surprised at the price of these dampers when I started looking. This was the best deal at $225. Well worth it, however, for preventing a draft.
