Legends (P.S That 'Empire State Building' photo isn't the Empire State. It was taken a year or two before the Empire State build started and is of a different skyscraper building in the same general area)
Funny thing about Americans, they actually do trust each other to be competent enough to bend the H&S rules, because they are that competent. They're not the best in the world, but they gain efficiencies out of having a really good attitude towards teamwork. And all their crews are unionised, in a country that hates socialism, jus'sayin.
This side of the ocean trusting your coworkers to not get you killed would be a rare thing.
And it's steel, not iron.
And they're called scaff clamps, not cheeseboroughs. GRRRR, Americans.
