A transport system may be provided for transporting spools of flexible material, such as wire or tubing, about a construction site and for dispensing the material from a spool rotatingly mounted on an angled support of the transport system. The angled support may form an acute angle at its lower end with a central member of a mobile assembly and an acute angle at its upper end and a central member of an upper assembly, so that the angled support and central members are vertically coplanar along a longitudinal centerline of the transport system. In this manner, more spools of material may be carried between the extents of the central members than would be possible if the angled supports were perpendicular to the central members. Furthermore, the angled supports may resist racking forces resulting from longitudinal movement of the system and from resistance to dispensing of material from the spools.
