I’ve had this rack for a bit over a week and it exceeds my expectations. The manual was well done and the assembly was much easier than I expected. With the help of my wife (only to hold 1 end piece up for a minute or two) we got the rack assembled in about 30 minutes. You simply align 2 shelf support wedges with 2 leg support “V” notches on each shelf end. The weight of the shelf self tightens the assembly.
I would recommend assembling all 4 back side shelf supports first, then assemble the fronts.
The design is excellent as the heaviest component was probably 25 lbs, yet the rack is rated for 8000 lbs. all this with absolutely no bolts nor nuts to fasten.
My only suggestion would be adding more plastic shelf liners (the shelves are made of heavy gauge welded wire shelves and the plastic liners allow small aerosol cans and bottles to avoid falling through).
