Create a complete Erecta Shelf shelving system with Erecta Shelf Uprights. Erecta Shelf wire shelves (sold separately) easily connect to the uprights without the use of any special hardware or tools. The open wire construction of Erecta Shelf Shelving minimizes dust accumulation and allows a free circulation of air, greater visibility of stored items, and greater light penetration. Shelves can be placed at 5" (127mm) intervals along the uprights. Durable chrome-plated finish. Important: When ordering by components remember that stability deceases as the ratio of height to width increases. Freestanding Erecta Shelf units should be kept as wide and low as possible.
