In 'as new' condition, these anchor posts are intended to attach cables and rope to. They are immensely strong, and will also serve as a fall-break. They can be bolted as shown. They may also be bolted on the underside of a beam, so a cable or rope can be suspended from the ring. I have three of them at $150 each - a fraction of the new price. They are left over components from a large engineered project, and are now taking up space. The last two photos show a similar product - but not identical, and just one possible use.
