Help yourself slam the door on soaring energy costs. The Lock-Top Damper makes a super tight seal with its silicone rubber gasket. This tight seal can reduce heat loss by 90 percent over even new traditional throat dampers. Traditional throat dampers have a metal-to-metal seal. They're leaky even when new and only get worse as they rust and warp with age. The Lock-Top has a stainless steel lid attached to a cast-aluminum frame by an array of stainless spring wires. It is operated by a 30' cable dropped down the chimney with a handle mounted in the firebox (Both Included). Just a tug on the handle will open or tightly close the Lock-Top.
