The Top Damper Plus Chimney Cap/Damper - 18" x 18"

The Top Damper Plus combines the efficiency of The Top Damper with the added protection of a stainless steel cap. This damper still seals out rain, snow and sleet while sealing in "paid" heat and air conditioning, but also provides added animal and debris control. What makes the Top Damper Plus so unique is the soft, pliable rubber gasket seal attached to the frame that compresses and conforms to the lid when closed, while also acting as a chimney cap. Designed with a cast-aluminum lid and stronger spring, this damper is easier to open and close while still creating an air-tight seal at the top of the chimney. When closed, this damper is a great solution for saving “paid” energy dollars for homes with leaky or missing dampers. Heat loss up the fireplace chimney accounts for an average 8% of your home heating costs - The Top Damper Plus helps prevent this heat loss. •Stainless Steel & Aluminum Construction •No Fusible Link / Quick & Easy Install •Energy Efficient / Tight Seal •Limited Lifetime Warranty 8″ X 8″ Fits inside flue from 6″ X 6″ up to 9″ X 9″ 9″ X 13″ Fits inside flue from 6″ X 9″ up to 9 1/2″ X 12 1/2″ 8″ X 17″ Fits inside flue from 6″ X 14″ up to 9″ X 17 1/2″ 13″ X 13″ Fits inside flue from 9″ X 9″ up to 12 1/2″ X 12 1/2″ 13″ X 18″ Fits inside flue from 9″ X 14″ up to 12 1/2″ X 17 1/2″ 18″ X 18″ Fits inside flue from 14″ X 14″ up to 17 1/2″ X 17 1/2″
