Both models of storm collar fit 6, 7 and 8 inch EXCEL chimneys.  To form an attic insulation shield assembly in an insulated space, use a storm collar in combination with a support box or radiation shield.  The ESQSC is required to form an attic insulation shield on a Square Support (ESS), all other supports and radiation shields can use either collar.  If installing 5" EXCEL, use the storm collar for EXCEL Direct (SC).
