Customer Q&A with Product Specialists

Darrell W. from asked:
Will this fit over a 13 x 13-inch cap?
Will this fit over a 13 x 13-inch cap?
The standard 13"x13" chimney caps often will not allow enough height to open the damper assembly fully. It is recommended that the damper be purchased with a cap combination.
