The Rock-Vent Storm Collar is made to fit the exact dimension of the pipe. Constructed of 304L stainless steel. Use to seal the inner edge that contacts the chimney pipe with silicone sealant. A storm collar is always included with our Flashings or Attic Insulation Shields (may be made of a different steel in those kits). Keep in mind, the sizes listed are always the inside diameter pipe size. Ex: The 8" storm collar will fit our 8" Rock-Vent insulated pipe which has an outside diameter of 10.5".
