System consists of one 60" hang track, three 60" vertical standards, and 8 shelves, four of them 35½”W x 8”D and the other four 24½”W x 8”D. Shelves are made of sturdy metal and can be attached to the standards with brackets facing upwards like bookends, or down.
The manufacturer of these shelves, Kernel, is now out of business, but the mounting hardware is all Container Store Elfa brand, so you could create a different configuration with any Elfa-compatible shelves or Elfa hardware.
