Although not a chimney cap, we include here the Lyemance Damper
specially designed for round, clay flues.

Lyemance Damper
for Round Flues

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. The Round Lymance Top Sealing Damper is designed for clay (or masonry) flues on woodburning (not gas) fireplaces.

When the 12" round Lyemance Top-Sealing Damper is completely open, it adds 4 ³/4 inches to the height of the flue.

The low profile of the Lyemance Damper blends into the roof line. Your Lyemance Top-Sealing Damper will arrive 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 damper handle shown at left. The Lyemance Damper is durably constructed of cast aluminum and fully guaranteed for material and workmanship.  All hardware and silicone sealant included. See EZ Open Lyemance Damper Handle, below.
