Column covers are manufactured in two halves. They are attached directly to structural columns utilizing (customer supplied) attachment angle and clips. Allow 4 inches clearance of diameter or 2 inches clearance on each side of the maximum corner-to-corner dimension of the structural column for attachment and return ends. The hairline/butt joint design (AP-COL-200) uses a ‘snap together’ design with integrated stem and groove. Design requires ¾” head clearance to slide the stem into the keyhole slot. (See standard details.)
