Lock Top II Chimney Damper

The Lock Top II Chimney Damper With Cap is the perfect solution for cold & drafty wood burning fireplaces. There's no question, old traditional metal fireplace throat dampers tend to be very leaky even when the damper is closed. Save money by installing the Lock Top Chimney Damper. As a matter of fact, a traditional masonry fireplace throat damper will leak $200 or more of energy a year. However, the Lock Top II Chimney Damper is equipped with a silicone gasket under the lid which makes for an extremely tight seal when closed. After installation, you will no longer feel a draft when the fireplace is not being used. Features 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
