The Lock Top Damper is the perfect solution if you are tired of your cold, drafty wood fireplace. There's no question, old traditional metal fireplace throat dampers tend to be very leaky even when the damper is closed.
Moreover, a traditional masonry fireplace throat damper will leak $200 or more of energy a year on average. The Lock Top Damper is equipped with a silicone gasket under the lid which makes for an extremely tight seal when the damper is closed, saving you money.
Features
Not only will this fix your downdraft concerns for your wood fireplace, but we make it easy to get the installation done. All in all, the hardware is included for an easy installation. Moreover, the only tools you will need to install the damper are a pair of wire cutters, drill, 1/4" masonry drill bit, and a hammer.
Not only is the cable made from heavy duty stainless steel, but also it is capable of withstanding extreme temperatures, it will not burn out. In addition, the base is constructed of heavy duty cast aluminum and the lid is constructed from stainless steel. Whether you are looking for a simple solution, or an affordable solution, the Lock Top Damper is a great choice.

Operating Your Lock Top Damper
Firstly, mount the Lock Top Chimney Damper on the top of your chimney flue. Secondly, adjust the chain handle to the bracket you mount on the fireplace wall. Finally, lock the cable in the fireplace bracket when you want to close the damper and release the cable from the bracket to allow the damper to spring open when you are ready to have a fire.
Most important, this is intended for use with traditional masonry wood burning fireplaces. In addition, do not use with gas appliances or gas logs.
Note: Do not use Lock Top dampers with gas logs. For example, failure to open the damper with gas logs could result in carbon monoxide in the home. Also, in the event of a gas leak & gas is trapped in the chimney, it could result in an explosion.

Options for Your Lock Top Damper
RS Round Flue Adapter (Optional):
Although Lock-Top Dampers are typically installed to your square or rectangle flue, many chimney flues have round clay tiles, pipes, or solid packed Class A double wall pipes. As a result, the RS Round Adapter is a simple solution for this type of installation.
Firstly, use the RS Round Adapter by simply sliding it inside the round flue opening. Secondly, you will attach the energy-saving Lock-Top damper to the square (top) of the RS adapter.
RS Round Flue Adapter Sizing:
To begin with, select the RS Adapter by the inside diameter of the flue or pipe opening. Another key point, the RS adapters are NOT to be used with Air Cooled Pipes. If you need an Air Cooled Adapter, please contact us for a quote.
Nevertheless, give us a call if you would like help sizing for a RS Adapter.
