We now use this for top mount dampers and it is a great product. We use this brand for its fair price and ease of installation. It uses a cap/screen-spark arrestor with it, meeting NFPA 211 code requirements, other brands do not. It comes in a variety of sizes and is made with stainless steel and comes with a manufacturers lifetime warranty. It will reduce heat loss in the heating season and according to one of our customers it greatly reduced her heating and electric bills.
The same sturdy, reliable, rugged, and easy to install, all 304 stainless steel single flue chimney cap with a damper built in. Comes with 32 feet of stainless steel cable, 3 feet of stainless steel cable guard to protect the cable at the flue offset, and 10.5 oz. tube of XtraBond 250 silicone sealant.
Huge heat loss occurs when a chimney damper doesn’t seal properly or is missing or broken. A new to-sealing damper will normally pay for itself the first year from the savings on the heating bill alone.
Easy to install, all stainless steel top sealing damper. Doesn’t downsize the flue. Seals air tight and takes only 13 lbs of pull to open or close.
