the fireplace draft stopper is an inflatable urethane chimney plug balloon pillow measuring 38" x 16". A round fireplace plug is also available. It is quickly and easily installed in the fireplace just below the damper level.
the fireplace plug can be adapted to work in almost all fireplaces. Even if you have an unusual construction, the fireplace plug can be successfully installed in less than 2 minutes.
the fireplace plug is provided with 5 "slittable" areas that can be cut to provide an opening for a damper handle. As the draftstopper is inflated it seals around the damper handle sealing the opening!
