Product Overview
The ZY-B-02 Trackless Double-Row Manual Mobile Shelving System delivers back-to-back double-sided storage in a single compact unit, ideal for large-volume archive centres, government record rooms, university libraries, and enterprise document management facilities. Its back-to-back shelf configuration effectively doubles the storage density of the ZY-B-01 single-row model within the same floor footprint, making it the preferred solution where maximum document capacity is required. Fabricated from premium SPCC galvanised cold-rolled steel with a depth of 1230 mm to accommodate dual-access filing, the ZY-B-02 retains the same proven chain-drive handwheel mechanism and all-welded structural integrity as the single-row variant. All components arrive flat-packed for cost-effective container shipping and straightforward on-site installation without specialist equipment.
