•These ThoroShield® curtains are shipped broken down and DO require assembly prior to installation.  The metal frame consists of .813” and 1.0” galvanized steel square stock sections that must be slid into each other until a complete “circle” of steel is assembled into a rectangular shape.  By “circle” we mean that if you start in the lower right corner and move counterclockwise around the frame you will find the sections alternate from .813 to 1.0 to .813 to 1.0, etc. until the frame is complete.
