A simple, adjustable regulator that is mounted on the fireplace's side wall conveniently controls the Chim-A-Lator Deluxe, which mounts effortlessly on top of masonry fireplace flues. It is the best replacement for old, broken dampers since it is significantly more effective than traditional cast iron dampers. Known to be the most trouble-free top sealing damper for more than 40 years.

This offers several benefits for your fireplace while also safeguarding the inside of the chimney. They serve as a wall separating the interior of your chimney from the outside environment. The duct that allows smoke to leave the structure is located beneath the cap.

It is possible to successfully maintain the surface of a chimney by letting less dirt and water inside. Because of this, the air vents continue to function as they should and the cost was significantly lower than replacing a damaged one.
