Lyemance Dampers with FREE Shipping

The superbly engineered Lyemance Top-Sealing Damper eliminates up to 90% of the air loss of a traditional damper. Let this easy-to-mount damper lower your winter heating and summer air conditioning costs. The Lymance Top-Sealing 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 Lymance Dampers are sold each year.

Lyemance dampers in eight sizes, the top-sealing damper that eliminates up to 90% of the air loss of a traditional damper.

 

The Lymance 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 Lymance Damper always opens easily.

Coil-Style Lyemance Damper handleThe Lymance Damper can be installed on chimney tops in minutes, and used with new or existing fireplaces. 

Available in sizes to fit most standard flues, including round. The low profile of the Lymance Damper blends into the roof line.

Lymance Dampers are completely assembled with a 32 foot cable (longer cables also available, below), a tube of silicone sealant to bond the damper to flue tile, and the coil-style handle shown to the left. The Lyemance Damper is durably constructed of cast aluminum and has a Lifetime Warranty for material and workmanship.  All hardware and silicone sealant included with each Lymance Damper. 

See the Lyemance Damper EZ Open Damper Handle, below.

Discount prices on Lymance Dampers and accessories. Lymance Top Sealing Fireplace Dampers reduce energy loss plus they Ship FREE to continental United States.
