Send Smoke Away and Keep Heat In

Made to seal chimneys when fires are out so the cold air doesn’t come in, this important element of a high-functioning fireplace comes in three different types: cast iron, top-seal, and anchor plate with damper.
Important to note about our dampers is:
  • Cast Iron Dampers can be used for all fireboxes with the exception of our 72” conventional, which requires two top-seal dampers; and our See-Through models, regardless if using masonry or metal flue
  • Top Seal Dampers are compatible with all fireboxes that use a masonry chimney system
  • Anchor Plate with Dampers are compatible with all fireboxes that use a metal chimney system
  • All Vent-Free and Outdoor FireRock models do not require dampers
