The rack looks have been made with costs in mind. That being said, I am perplexed as to why an 8ft. long( wide ) rack was sent when I specifically ordered TWO of the 6ft. wide size. So I have two extra 2ft x 3ft panels that are not being utilized and have no use for them. They are made as 2-8ft wide size range where you end up paying for what you don't use. It was quite confusing until I figured out what was going on as I ordered two and they arrived days apart. The description says it has an adjustable height but not width. There were just two options to order. The first being 36" H x 72" W x 36" D OR 36" H x 96" W x 48" D. They could have cut the cost down for purchasers of the 6ft size by providing only what is ordered. I have seen what appeared to be better built options online, only the were not offered in the 3'x6' size I wanted & needed. They do the job though, & are very rigid and strong. I am happy about that, so my wife can finally get her car in our garage. I had to mount the three back side ceiling brackets perpendicular to the two front bracket for the 3ft deep size due to the 24" on centre truss rafters. This gave me a solid 4-way no wobble storage rack( rigid ! ) See my pictures. Bracket for a third storage rack are in place for another 6ft rack but 4ft Deep. That rack was supposed to be just 46" Deep but I received a 48" Deep unit. A call into customer service and the representative made everything Ok by applying some discounts for the errors in sizing. So, in the end, and overall, I recommend these products
