Wide Span Rack, no deck, 1100 lb cap,
Your review: Incredibly easy to assemble by 1 person.
Boltless connectors actually increase in structural rigidity as more load is put on them.
Recommend the center shelf connector and plywood shelves. Cut plywood shelves so that grain is parallel with depth measurement ( increases load capacity)
Dollar for dollar , this shelving unit outperforms any home-made unit.
Just do it.
