Seal Tight and EnergyTop fireplace dampers are designed only for use on masonry fireplace chimneys and are installed by attaching to the flue tile liner. A chain drops down the chimney and is secured inside the fireplace with a bracket that provides each access to the cool-touch spring handle.

Our top mount dampers provide a better seal against invading animals, birds and insects; they'll help keep your heat and air conditioning in your house and protect your chimney interior from the ravages of weather related damages. Our dampers offer a tight, gasket seal fit to outperform throat mounted metal dampers, year after year.
