Just to add, I returned 1 set of my 6 ton hf stands that are under recall, and bought a set of the 12 ton as a replacement, the teeth are a cast a tad bit deeper, (compensating for the obviously much larger teeth) but the lever is still a little above center when seated.
I have used hf, and various other brand jack stands for over a decade. These 6 ton jacks are under recall so I took advantage but I’ve never had an issue.
Something everyone needs to know and practice is using redundant jack stands in place as a backup.
Even the sumner and rigid pipe stands NEED a redundant stand as a failsafe when supporting anything a person may be working under.
At work we support load above people and our safety factor is always 10/1
