Monsoon Cap

A replacement lid for our standard chimney cap for metal chimneys that turns it into a
“Monsoon Cap” to keep out driving rain. Just change them out with the one wingnut on top.

The “Monsoon” cures most wind related down draft problems. Its design actually increases draft as the win speed increases. So if the smoking problem is wind related, the “Monsoon” and a Smoke Guard usually handles it.
