NOTE 1—ModelApanels normally have horizontal reinforcing folds (or beams) to increase horizontal rigidity. Number of folds (beams) increase with
the height of the panel. Generally two folds for panels shorter than 5 ft [1525 mm], three folds if shorter than 6 ft 6 in. [1980 mm] and four folds for
taller panels up to 8 ft [2430 mm].
NOTE 2—Model B panels have vertical wires sandwiched between two (2) horizontal wires.
NOTE 3—Model C panels have straight wire in both directions. Panels have variable wire spacing in panel height.
