The Chim-A-Lator Deluxe fits perfectly on top of masonry fireplace flues and is controlled by a straightforward, adjustable regulator mounted on the fireplace's side wall. Since it is significantly more effective than typical cast iron dampers, it is the perfect replacement for old, damaged dampers. For more than 40 years, the most trouble-free top sealing damper has been demonstrated.

Fireplace coverings can be used in a variety of ways to protect the chimney's interior. They act as a wall dividing the chimney's interior and exterior. The building's roof has a vent that lets air out.

The firebox cover conceals this aperture, keeping it dry and protecting the chimneys. If water in a chimney corrodes the bricks and cement, the internal structure of your home could be in jeopardy. Damage may also occur to the fireplace's walls, roof, firebox, flue, dampers, and other components. It should be clear why this is an important component of your chimney system.
