Use the square storm collar when the square ceiling support is also being used as an attic insulation shield.
A Note on Attic Insulation Shields: In many installations the ceiling support may also serve as an attic insulation shield. The ceiling support must extend upward 10” above the attic insulation and the top of the ceiling support must be closed off with a storm collar. A round storm collar or a square storm collar can be purchased separately to fit the respective ceiling support style.
