whoa now $711?? ...those are just a trifle expensive, eh??
Very confusing. are those stands USA made or not? They don’t admit to having a factory here.

X10. Unfortunately any mass produced jack stand is going to be made just strong enough to save on manufacturing costs. And it may use less than ideal manufacturing processes (like look at the crappy production mig welds in some of the pictures). That's why its best to buy much higher capacity stands than you need for that extra safety factor.The TRUEST part of the article--
"Ratcheting stands tend to be more convenient, but selecting a pair of stands which use pin and hole, or pin through, technology will give you the highest safety rating."
IMHO, for lighter and smaller vehicles, a quality pair of ratcheting stands are probably fine...that said, WHY mess around with anything but pin type jack stands with the weight of our beloved and mighyty Cummins overhead??
The Gray 10 ton stand says it is 10 tons each and the pair weigh 70 lbs. The Hein Warner 6 tons is per pair, but if you look at the label on the 6 ton stand it doesn't clearly state it is per pair. Typical of BS marketing and a good reason to doubt any claims that company makes.
Safety Standard for Portable Automotive Service Equipment states that jack stands must be rated as a pair and not rated per stand. This became effective in late December of 2015. It also states: “Maximum load capacity per matched pair shall not exceed the rated capacity of the individual stand”.
Separate from that, test standards require that each jack stand must be able to pass a proof load test of 200% of rated capacity for a minimum of ten minutes, with no more than 0.125” reduction in overall height of the jack stand. This is measured after removal of the load. This is actually a separate testing requirement from the rating standard as a pair.
the jack stand base is made overseas and the cast iron support post is made in the U.S. The base is then shipped to the Hein-Werner factory in the U.S. where the jack stand is assembled (insert post in base) and boxed at the Hein-Werner factory and gets the aforementioned labeling.
All these standard companies are for profit, its pay to play deal. They are for sure not a impartial 3rd party looking out for our personal best interests.Interesting tidbit I found the other day.
This was quoted from a website , I
tried looking up ASME PASE standard and was politely told I needed $170 to view....uh...no thank you.
Also came across this regarding Hein Warner. I don't know if it's true but if it is it's quite misleading on their end.

Good find. ASME PASE or PALD? Clear as mud. So if a stand meets the current ASME standard then each stand cannot have a lower individual rating than the rating for the pair. And each stand has to hold twice its rated load for 10 minutes without major deformation. So in theory each stand has a minimum of a 2 to 1 safety factor at the full load that the pair is rated for. I read somewhere that ANSI was lower at 1.5 per stand, but couldn’t confirm if that was in the past or if it is still true today.Interesting tidbit I found the other day........Safety Standard for Portable Automotive Service Equipment states that jack stands must be rated as a pair and not rated per stand.

ANSI, UL, ASME, NEMA, SAE keep going and you will find the same crap, all these standards should have a free abstract of the basics, they in most cases do not.
The fees I have paid for my UL listing via ETL supervised by Intertek is insane. But we require the damn little sticker so is what it is.
The 7T Gray are insane rating as a pair.....
They do list them that way as well for the Gray.

Just bring them in. Just returned a set on Monday. Gave me a gift card for 39.97 + tax. Of course, they had no new stock in the store. As a matter of fact, the store was sparsely stocked. The clerk said they're very backlogged at the distribution centers.Is receipt needed for the return of these stands?... or show up with stands and hand them over...
