A vertical column member having sets of vertically spaced mounting brackets mounted thereto. Each mounting bracket has at its inner end two resilient arm portions, each having a laterally extending mounting lip, with the two lips fitting in a related pair of channel members that define a slideway. Between each pair of adjacent vertically spaced brackets, there is positioned a spacing and locking element which holds the two arm portions in positive engagement with the channels of the slideway. By moving the locking and spacing element out of engagement, the inner arm portions can be sprung inwardly and the bracket removed from the slideway. |
