Quite often builders don’t remove these, claiming they will be useful in the future.
I’m wondering what the useful lifespan of these straps is. I’d google the manufacturer but I don’t know who makes them.
John,
Some fall protection roof anchors manufacturers at link below claims that they will last the life of the roof.
