wall at the top Each pair of vertical members will allow the attachment of front panels, chassis and subracks, in accordance with this series of standards The coordination dimension of the fixed rack structures is equal to the theoretical centre distances within a suite of racks Each vertical rack member may be separated from or combined with the vertical member of the adjacent rack, providing the width coordination dimension is maintained The heights and depth of such structures are not covered by this standard Table – Width dimension of fixed rack structures Dimensions in millimetres Width
