Vacu-Stack 8" with 1/2" x 1/2" Single-Flue Round Screen

The Vacu-Stack Chimney Cap with Screen is the best solution for wind induced downdrafts on both masonry and prefabricated chimneys. It is designed to stop wind from blowing into the chimney regardless of the wind direction. Accelerated air flow around the Vacu-Stack causes flue gasses to flow up and out of the chimney.

This model is designed for a round Class A Double Wall Chimney and can be used on a masonry chimney with the proper adapter sold separately.
