for Square, Rectangular, and Round Flues with FREE Shipping
The superbly engineered Lyemance Top-Sealing Dampereliminates up to 90% of the air loss of a traditional damper.Let this easy-to-mount
Lyemance damper lower your winter heating and summer air conditioning costs. The Lyemance damper also eliminates down drafts and keeps moisture and
animals out of your chimney and home. Moisture in your chimney causes unwelcome odors and leads to deterioration of bricks and mortar. The Lyemance
Top-Sealing Damper works year round to protect your chimney. That's why thousands of Lyemance dampers are sold each year.
The Lyemance damper, featuring the Power Lever, is easily opened and closed by using a stainless-steel cable that
extends down the flue to a bracket fastened on the side of the firebox. With the Power Lever, a tug on the cable drives a piston upward, applying a whopping 143
pounds of leverage, so the damper always opens easily.
The Lyemance Top Sealing Damper can be installed on chimney tops in minutes, and used with new or
existing fireplaces. Available in sizes to fit most standard flue liners, including round. These are designed for clay (or masonry) flues on woodburning (not
gas) fireplaces.
