Duravent is proud to announce the Square Ceiling support box now with a new and improved Square to Round Insulation Collar! This new collar design provides better protection from debris entering the support box.
Use with flat, vaulted, or cathedral ceilings where there is attic space above. Supports up to 40’ of DuraTech Chimney.
The additional Insulation Collar now enables the support box to be qualified as an Attic Insulation Shield. The additional Attic Insulation Shield (DT-AIS) is not required with these support boxes.
