A wire tray and tent frame structural members are provided. The structural members include a utility channel or C-shaped channels to which wire trays can be mounted. More particularly, mounting structures of the wire tray insert into or otherwise engage the utility channel or engage the C-shaped channels and secure the wire tray to the structural members. The utility channel or C-shaped channels can include at least one undercut to prevent removal or disengagement of the mounting structure of the wire tray from the structural member. Similarly, methods of using the wire tray including resiliently biasing mounting structure of the wire tray to attach it to the structural member are provided.
