Product Details:

Are you tired of your cold and drafty fireplace? The Lock Top II Chimney Damper With Cap is the perfect solution for wood burning fireplaces. Old traditional metal fireplace throat dampers tend to be very leaky even when it appears the damper is closed. On average a traditional masonry fireplace throat damper will leak $200 or more of energy a year. The Lock Top II chimney damper is equipped with a silicone gasket under the lid which makes for an extremely tight seal when the damper is closed, you will no longer feel a draft when the fireplace is not being used. Not only will this damper prevent downdrafts and energy loss, it is also equipped with a single flue chimney cap with 3/4" spark arrestor to prevent sparks from exiting the chimney while also providing weather protection. The cap will also prevent critters from entering the chimney if you forget to close the damper after you have had a fire. The cap is removable from the damper for servicing.

The Lock Top II Chimney Damper includes 30 ft. cable, adhesive, mounting hardware and a Lifetime Warranty. A Sweep's Ring is also included with the Lock Top II damper cap. The Sweep's Ring allows you to fully remove the damper and cap without having to cut the adhesive holding the damper to the flue off to remove the damper cap. The Sweep's Ring Gasket will attach to the flue with the adhesive (included with damper) and the damper will simply bolt to the Sweep's Ring gasket.

Simply mount the Lock Top II Chimney Damper on the top of your chimney flue and adjust the chain handle to the bracket you mount on the fireplace wall. 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. The heavy duty stainless steel cable is capable of withstanding extreme temperatures and will not burn out. The base is constructed of heavy duty cast aluminum and the lid is constructed from stainless steel. All the hardware you will need to install the Lock Top II Damper is included. The only tools you will need to install the damper are a pair of wire cutters, a drill with a 1/4" masonry drill bit, and a hammer.

Intended for use with traditional masonry wood burning fireplaces. Note: Do not use Lock-Top II dampers with gas logs (failure to open the damper for gas burning appliances could result in carbon monoxide to back up in the home. Also, in the event of a gas leak, could result in gas being trapped in the chimney which could result in an explosion.)

RS Round Flue Adapter (Optional):

Lock-Top Dampers are installed to your chimney flue, many of the flues are rectangle or square in shape and the dampers are easily attached to the chimney or clay tiles. However, many chimney flues have round clay tiles, pipes or solid packed Class A double wall pipes, we now have a solution for them - the RS round flue adapter.

Using the RS Adapter, simply slide it inside the round flue opening and attach the energy-saving Lock-Top damper to the square (top) of the RS adapter. Select the RS Adapter by the inside diameter of the flue or pipe opening. The RS adapters are NOT to be used with Air Cooled Pipes. Please contact us for a quote for Air Cooled Pipe Adapters. Give us a call, if you would like help sizing for a RS Adapter

The 6"-8" adapter plate size is 9 1/2" x 9 1/2". The 9''-12" adapter plate size is 12 1/2" x 12 1/2".

Great for real winter

Internal damper rusted out in cold, snowy country. This one seals the drafts much better and survived the deep snow. Keeps the birds out, too.

Awesome product

Solved a problem I had with an internal damper rusting out like swiss cheese. This thing installed on the chimney in minutes and then another 20 minutes to install the pull cable. I recommend this to anyone. The nice part is, it comes with the clean ring so I can unbolt it and take it off for chimney cleaning.

Easy to install, works great

It was easy to install and works great.



We had a noticeable backdraft on warm days that caused a noticeable smoke smell in the house. The Lock top II has eliminated this problem.
