Abstract: In one embodiment, a mounting bracket for mounting a horizontal support member between vertical support columns of an equipment rack. The mounting bracket comprises a base member and a latch. The base member comprises integrated side and end plates, with the side plate being securable to the horizontal support member and the end plate constructed to vertically support the mounting bracket thereon. The latch detachably adjoins the mounting bracket to the vertical support column, and is constructed to be hand-operated to detach the mounting bracket from the vertical support column in response to a tool-less manual manipulation of the latch.
