Quantum's high density storage system is a build-your-own wall of hanging bin storage: louvered panels, bench racks, free-standing single and double sided racks, and individual steel rails that mount almost anywhere. Every component accepts Quantum Ultra Stack & Hang bins, so you can start with a single 48" rail over a workbench and grow into a mobile double sided rack that rolls between departments.Panels and racks are offered in Quantum's standard gray finish, with several louvered panels and the steel rail also available in oyster white (the -HC models) to match lighter décor and lab environments. The QRU-MOB mobile kit converts double sided racks into rolling pick stations. Bins are sold separately, letting you mix bin sizes and colors to suit the parts being stored.
