ahem, the steel ring i posted is TIG welded INOX steel , from 11mm rod stock and it is load rated. The INOX ring 12,500 LBs MBS, the plated steel ring 8500lbs MBS, both are WELL over the OSHA and ANSI ratings for treework.
as well, when i contacted the manufacturer, they stated the ring was for setting up anchors or rappel points and that it was perfectly usable as a tree anchor point (AKA friction saver) . When we set up a friction saver in a tree, that IS a rappel point or anchor (wether treeguys like to call it that or not, thats what it is...). So using these big beefy steel rings IS PERFECTABLY ACCEPTABLE. The exact same ring is used in industrial settings, rescue, fire evac etc.
as for the ANSI stamping on equipment......i have YET to see ANY tree equipment , be it slings, biners, harnesses helmets etc stamped with ANSI logo...
only thing i got with ANSI logo is my steel toe rubber boots....and ALL my treegear is STANDARD , readily available in any arb store, tree gear that is used EVERYDAY all over the world....
