Description

This swing door damper is made of cast aluminum and comes with a 32' stainless steel cable. The cable is connected to the spring-loaded Power Level Damper.

Includes mounting hardware and sealant. Note: Do not use top mount dampers with gas logs. Intended for use with traditional masonry wood burning fireplaces.

Make the removing of the damper quick and easy for chimney cleaning and inspection by adding a Sweep's Ring Metal Gasket. The Sweep's Ring Gasket will attach to the flue with the adhesive (included with damper) and the damper will simply bolt to the gasket. Check the option box below to add this to your damper.

  • Easily mounts atop flue tile
  • Lifetime warranty
  • Silicone rubber seals tight
