8" x 17" Lock-Top II Chimney Cap-Damper

The Lock-Top II Chimney Cap/Damper arrives fully assembled and ready to install. Its base mounts to the sweep's ring which attaches to the flue tile with silicone sealant. A 30' stainless steel cable drops down the flue, and a hardware set mounts in the firebox. The end result is a damper that opens and closes with ease at the tug of a drop down cable. The Lock-Top II is equipped with a fire safety device that enables the damper to remain open in case of a chimney fire.

*Top-sealing dampers are not recommended with gas logs- failure to open could cause carbon monoxide to back up into the house.
