The No-Cling vertical ribs are on both sides of the flight.
Each flight extends from the center of the module, molded as one part. No fasteners are required.
Flights can be cut down to a minimum height of 0.5 in (12.7 mm).
Flights of even-inch widths come standard with 1 in (25.4 mm) indents. Flights of odd-inch widths are available for retrofits and require machined indents, which contain marks and evidence of modification.
