The web comprises at least one length of metal bar stock having zigzag bends. A first set of bends is disposed along a first margin of the web and a second set of bends is disposed along a second margin of the web. The first chord comprises at least two struts, with one on each side of the web at a respective web margin. Each strut comprises a metal channel having generally opposing walls having inwardly directed lips at their outer ends. The lips are spaced from one another to define a slot extending the length of the strut. Each strut is secured in engagement with the respective side of the web and is adapted for insertion through its slot of items to be retained in the strut.
