The Open and Shut Solution to Fireplace Problems!

Made of cast aluminum and stainless steel, these dampers are meant to brave the elements year round so your chimney doesn't have to. The Lock-Top damper uses a high quality silicone rubber seal to ensure a tight fit and prevent anything from making it's way in. It also includes a cap and mesh surround to keep out rain and pests while the chimney is in use or while cooling. These dampers come with a Limited Lifetime Warranty.

The Lock-Top II comes fully assembled. Its base mounts to the included sweep’s ring which attaches to the flue tile with silicone sealant (included). A 30' stainless steel cable and hardware are also included. All Lock-Top II cap/dampers have an overall height of 11-3⁄8".

Note: Don't use Lock-Top dampers with gas logs - failure to open could cause carbon monoxide to back up into the house. In case of a gas leak, gas could be trapped in the flue, resulting in an explosion.

Chimney dampers allow you to close the chimney flue when the fireplace is not in use to prevent heated or cooled air from escaping the home through the chimney. An open flue is an invitation for inefficient climate control and added problems due to prolonged exposure of the chimney to the elements. Using our large inventory of chimney dampers, you can make sure that you get the most out of your chimney and your home year round.
