Lock-Top 09120 Stainless Steel Lock-Top 13" x 13" Energy-Saving Damper 09120

Traditional dampers are located in the "throat" of a chimney. They are made of cast iron and housed in a low-tech frame. These cast iron shock absorbers do not seal well: they have a leaky, rough metal-to-metal seal. Recent laboratory studies have shown that even a new throat damper can leak up to $200 in heating and cooling a year. Imagine how much energy an old, rusty shock absorber leaks! Airtight energy saving dampers seal tightly to save you money. The Lock-Tights rubber gasket seals tightly like a storm door for your fireplace, and keeps your heating and cooling dollars where they should be... in your home. LockTight mounts to the top of your fireplace to keep animals and rain out, and works easily from inside your firebox, sealing tightly every time you close it, eliminating any draft. Stainless steel is the most popular cap material due to its longevity and flexibility of the fuel it burns. Which means if you have a wood burning fireplace and switch to gas logs, the stainless steel cap can handle the switch without worry.
