MightyVent 4″ UL Driving Cap

$35.00

The MightyVent AF 4″ driving cap closes off your MightyVent 4″ chimney for travel or seasonal storage on RVs, skoolies and boats. Remove the chimney parts above the roof or deck, then slide this one-piece 304 stainless cap over the top pipe section and lock it on with the included clamp. It fits MightyVent 4″ pipe only.

*** Limited Availability: Initial stock of the new UL parts line is limited, so it’s currently only available if you’re purchasing a Dwarf Stove. Use another brand of stove with 4″ pipe?

What a driving cap does

When you’re traveling or closing up for the season, swap the chimney parts above the roof for the driving cap. Its low profile holds up to highway wind, and it keeps rain, debris and insects out of the flue. Never light the stove with the driving cap on.
