An improved communications equipment relay rack includes a pair of parallel elongated columns. The columns are held upright. A mounting ear is secured to each upright column. The mounting ears are at substantially the same level in a horizontal plane extending through the ears. A support peg is fixed to each mounting ear. Each of the support pegs extends toward the other support peg. A shelf is mounted between the upright columns. The shelf includes a floor having a pair of opposed edges. A mounting side is secured to each of the opposed edges. Each mounting side is substantially perpendicular to the floor. Each of the mounting sides has a shelf mounting aperture receiving a support peg to hold the shelf between the columns.
