DuraVent DuraFlex Stainless Top Plate and Storm Collar: a welded collar keeps the liner supported during sweeping
The DuraVent DuraFlex Stainless Top Plate and Storm Collar is a square chimney top plate with a welded storm collar, the ring that holds the liner. The plate seals the top of the brick or block chimney. A band on the collar grips the liner and supports its full weight. The removable rain cap clamps onto that collar rather than onto the liner itself. That lets the cap come off for sweeping without taking down the liner. 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 3, 4, 5, 5 1/2, 6, 7, or 8 inch diameter to match your liner. The plate’s edges can be trimmed or folded over the brick, with high temperature silicone beneath the plate to seal it against the chimney top. This plate and collar are sold here on their own. Need the cap that attaches to the collar? See the DuraVent DuraFlex Stainless Removable Vertical Cap. The DuraVent DuraFlex Stainless Top Plate and Storm Collar ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
