Steel frame section for switching cabinet stand

摘要

A steel frame section used to make racks for switching cubicles has rectangular cross-section, with a narrow side (11) and a wide side (12) forming the inner edge (13). One narrow side is extended to form a sealing or locating surface. The width of the narrow side is at least half that of the wide side. The width of the narrow side plus that of the sealing surface equals that of the wide side. Both sides have series of openings for attachment to the base, close to the inner edge. In addition, the narrow side without the sealing surface may have openings aligned with those on the opposite side, but with twice the pitch.
