Energy Top Damper

The National Chimney Energy Top Damper is a low-profile top-mounted damper that also serves as a chimney cap. In the closed position, it is virtually invisible from the ground. It provides a tight, gasketed fit that seals heat. The National Chimney Energy Top Damper seals out weather, insects, birds, and animals.

A slight pull on the chain releases the spring-loaded top into the open position. When open, this damper design is least obstructive to exiting smoke. The damper includes a Lifetime Warranty, 30’ cut-to-fit cable, fireplace bracket, cool touch spring handle, mounting adhesive, and hardware. Do not use on a chimney venting gas logs.
