Instead of old, outdated, inefficient cast iron dampers, at Ryan and Son, we install Lock-Top Top Sealing Dampers. These dampers are highly effective at keeping heat in your home when the fireplace is not in operation. Making a gasketed air-tight seal at the top as opposed to the bottom, the Lock-Top Damper ensures the flue is kept at house temperature instead of the cold winter temperature outside, which aids in creating an immediate draft when the damper is opened and you light your fire.
For smaller chimneys with single flues, Lock-Top also manufactures a Damper Cap, which has the animal screen and rain lid included in one single setup.
