DuraVent B-Vent Storm Collar

DuraVent B-Vent Storm Collar is used to seal around the DuraVent B-vent pipe as it passes through either a roof flashing or a chimney chase cover. Silicone will need to be applied to make a seal around the storm collar where it meets the pipe above the cover or flashing. Choose the size of the storm collar based on the outside diameter of the pipe.
