Abstract: To form a U-channel storage system, a pair of U-shaped metal channels are disposed and secured a selected parallel distance apart, having paired equal lengths. The paired channels secured with their channel bases turned outwardly opposed, are secured to a flat wall surface, a conventional hand operated upright dolly, a tradesman's utility truck, or the like support means. Multiple open slots are formed in the opposed juxtal channel leg positions in the channel bases, spaced a selected distance apart. Multiple paired supporting stops are secured inside and across the U-shaped channels another selected uniform distance below each slot, providing a paired holding and supporting stop for a rod member of the required length inserted in each juxtal opposed pair of slots. Reels of wire, rolls of electrical conduit, tool boxes, wire caddies having suitable selected length of caddy feet, and other tool and instrumentation devices can be arranged on and held by rod members on the pair of securing U-channels.
