Claim:
An assembly kit for building a rack, comprising: a plurality of longitudinal members to be arranged vertically for interconnection to a plurality of cross members to be arranged horizontally, and a plurality of rails configured to accommodate rack bottoms or drawers, wherein: the longitudinal members are provided with holes used to hook in the rails on first lateral surfaces of the longitudinal members facing each other, the holes in the longitudinal members define T-shaped holes in top view and include vertically extending sections leading to horizontally extending sections that form breakouts in second lateral surfaces of the longitudinal members, with the second lateral surfaces being adjacent to the first lateral surfaces, the rails are longer than an open distance between a front longitudinal member from a rear longitudinal member by a depth of the breakouts and are provided with U-shaped folded edges, each of the folded edges including a substantially horizontal portion extending from an upper portion of a respective rail and a substantially vertical portion extending downward from the substantially horizontal portion thereby defining an open width which corresponds to sections remaining in the first lateral surface on both sides of a respective one of the vertically extending sections of the T-shaped holes, and a width of the vertically extending section of the T-shaped hole corresponds to a length of the substantially vertical portion of the U-shaped folded edge.
