18" x 18" Wiles Top Mount Damper - RD1818

The Wiles Damper is an energy-saving, easy-to-install, visually-appealing, top sealing damper cap that helps save on home heating and cooling costs. It keeps the heat and energy in, and the rain and animals out. Made of cast-aluminum and stainless steel, it features a unique spring design that ensures a better seal for your chimney. You will only need approximately one inch above the top of the damper to ensure the lid can fully open.

The damper features a silicone rubber U-shaped gasket that has a wide temperature range and is rated for use outdoors. It grips the damper collar better and provides a far better seal than most other gaskets available.
