High density rolling shelving on wheels saves floor space by allowing you to push a button or crank a handle to move the floating aisle to access the aisle you need to access. Systems like this cost less than file cabinets on a per linear foot of storage and allow you to store 3 times more in the same floor space. A system like this is a real aisle saver. It takes the wasted air space in the aisles and turns it into storage space. For more information visit our site at SHELVING ON WHEELS
Another concept is our Sliding Shelving on wheels that also increases storage capacity in the same floor space. SLIDING SHELVING ON WHEELS
