Lock-Top Dampers - The Whole Story

See why most dampers perform poorly and cost you money.
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.
Cast-iron plate and frame do not seal tightly, allowing energy dollars to escape.
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!


The Lock-Top Energy-Saving Damper seals tightly to save you money

Lock-Top mounted on the top of the chimney.
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.
Red, silicone rubber gasket under Lock-Top lid seals tightly to eliminate draft.
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.
