Ratchet-type jack stands

I guess then I would worry about stress concentration around the hole. It's just that when I see stands for $25, I wonder if they are designed properly. I know it shouldn't cost much to produce these things once they are designed, but still. I guess I am not making the "too cheap" counter point to the too expensive point, but there seem to be plenty of stuff in between. Anyway, just rambling I guess...

My Hein-Warners are about 30 years old and never a problem with them. they are far easier to adjust than the pin type.
