12" x 16" Lyemance Chimney Damper

The Lyemance Chimney damper will bring efficiency into your home and help conserve wasted time, money, and energy. The Lyemance Damer eliminates as much as 90% of the air loss of a traditional damper, proving to save you up to $100 in a single heating session. It is designed to lock in heat, while keeping rain, snow, and debris from entering the chimney. The Lyemance Damper can be installed in minutes and comes with a tube of silicone adhesive for mounting to the top of the tile liner.

The lid of the damper is spring-loaded and normally in the open position. It is shut by means of a stainless steel cable which extends down the inside of the chimney flue and is attached to a hook mounted in the fireplace opening. Each die cast aluminum damper is completely assembled and includes a 32' cable. Longer cables are available.
40' Cable 50' Cable.
