DuraVent DuraFlex Stainless Cap: the large size rain cap with its own support collar
The DuraVent DuraFlex Stainless Cap is a rain cap for a 10 or 12 inch liner at the top of a masonry chimney. It comes with its own storm collar, a banded fitting that grips the flexible liner and supports its full weight. The cap seals onto a separate top plate, which closes the opening around the liner at the chimney top. Its lid lifts off for chimney sweeping. DuraFlex Stainless is DuraVent’s flexible stainless steel liner for relining a masonry chimney that vents a wood, pellet, oil, or gas appliance.
Choose a 10 or 12 inch diameter to match your liner. These sizes fit the DuraFlex Pro liner ordered in custom lengths. The 304 and 316 liners only go up to 8 inches. Unlike the smaller fittings, which have the collar attached to the plate, this cap carries the collar itself. A spark arrestor, a screen that catches sparks, is not included. Need the plate beneath it? See the DuraVent DuraFlex Stainless Top Plate for the chimney top. The DuraVent DuraFlex Stainless Cap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
