Lock-Top Dampers - The Whole Story
|Traditional dampers are located in the "throat" of a fireplace. They are made of cast-iron and are housed in a low-tech frame work.|
|These cast-iron dampers do not seal well—they have a leaky, rough, metal-to-metal seal.|
|Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!|
|Lock-Top's rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should be...in your home.|
|Lock-Top mounts on top of your chimney to keep out animals and rain.|
|Lock-Top easily operates from inside your firebox and seals tight everytime you close it—eliminating any draft.
