• The main frame has one more column than the sub frame, which can be used alone.
• The sub frame needs to be used with the main frame. A main frame can be combined with multiple subframes to form a row, which saves cost and is more stable.
• Conventional matching: one main frame + N sub frames + two ends. Both sides of the double-sided main and sub frames can be connected to the end frame.

Shelves can be combined with a variety of accessories, such as hooks, floor cabinets, light tubes, light boxes and billboards. For more combinations, you can consult our customer service.
