The side skirts are mounted in 800mm wide cabinets next to the 19-inch profiles. They prevent the cold air from leaking along the 19-inch profiles. Each side skirt contains 3 x 2 HE 19-inch cut outs. The cover plates are not included and have to be ordered separately, for example the Minkels Fix Easy front panel MFE0102. Rubber cable grommets are placed at the top and bottom of each side skirt.
