LOCK TOP FIREPLACE DAMPER A less restrictive top mount damper system. When shut it serves as a damper, when open it serves as a rain cap. Easily removed for chimney cleaning, the Lock-Top Damper seals tight with a silicone rubber gasket, not metal to metal like your current damper. A Lock-Top Damper seals tight, so virtually no air - and thus no heat or air conditioning - gets lost up your chimney. The damper lid is spring-loaded and defaults to open position. Operated by a stainless steel cable which extends down the inside of the chimney flue (32' cable included) and is attached to a hook mounted in the fireplace.
Superior stainless steel and cast-aluminum construction equal a lifetime warranty.The Lock-Top Damper is made of cast-aluminum and stainless steel, precision fitted with a special silicone rubber gasket. These high-quality materials add up to a factory lifetime warranty for you.
Note: These dampers are specifically designed for woodburning fireplace flues and should not be used on flues servicing wood or coal stoves or on fireplaces serving gas logs.
Lock Top damper ships with silicone adhesive for installation to attach to top of flue tile liner; 32' cable & bracket to attach on inside fireplace wall.
Available in 6 sizes - see pricing and order details below. Measure your flue tile liner for the right damper to fit your chimney.
