Abstract

A positioning device is connected between an equipment unit and a vertical support column and includes a first board, a second board and a connection portion which is connected to the first and second boards. A first positioning portion extends from the first board and a second positioning portion extends from the second board. A hook extends from one of the first board, the second board and the connection portion. The hook contacts a rear end of the side wall of the equipment unit and the first and second positioning portions are connected to the vertical support column of the rack.

1 . A positioning device used on a rack, comprising:
