Fits our 4″ insulated pipe with a 6″ outside diameter.
The storm collar is attached to the insulated pipe just above the pipe boot or the metal roof flashing. The collar keeps elements away from the joint where the pipe meets the boot or flashing. A storm collar is optional with a pipe boot, but required for a metal flashing.
