Butterfly Cap-Damper


Just like the Butterfly damper, the Butterfly Cap-Damper gives you access to the chimney with the removal of a couple of wingnuts (below). Because of its design, the Butterfly Cap-Damper installs on either a chimney with a flue tile (liner) sticking up or one that does not have a tile above the crown. Just glue it on with the silicone that comes with it!

Constructed of 304 stainless steel, spring loaded, it’s simple for your customer to use and easy to install (just silicone it on).

Each damper comes with 32’ of SS cable. 3’ of SS cable guard for the offset of the flu, 10 oz. tube of silicone, firebox bracket pack; all you need are tools.

Huge heat loss occurs when a chimney damper doesn’t seal properly or is missing or broken. A new top-sealing damper will normally pay for itself the first year from the savings on the heating bill alone.
