After looking and looking you just can't get the quality shelving that was sold 10 years ago that did not need the bracing from rail to rail, with that being said for the money these were the best I could find and they will do a great job.I do wish I could buy just 1 more upright support and all the parts needed to add a few more shelves either 4' long or the same 77" long without having to buy another entire unit.
