I recently visited a salvage operation that handles all metal from near by army base--they had TONS of tools and fine stuff like new all SCRAPPED--so they can buy new stuff with the budget but anyway--They had a pile of first quality USA made jack stands as big as a garage--$10 a whack I filled the pick up
When I asked he said see the "cert" info on them--I looked and it seems they have been recertified for the weight --each one TESTED and re-certed every year --like they were going to go bad--well they do--so they were all scrapped--
I am guessing the tax payer spent a fortune buying them--then paid every year to have them re certed--then they scrapped them anyway--the best cared for jack stands in the world went bad so.......you want to go into the stand business?? Sell them to the ARMY You will be rich beyond your wildest dreams--To Hell with the public
