Yes. When doing steel tower work, a similar system is used.

Simply clipping bar over bar as you ascend the structure. If you “oops” there will always be at least one hook clipped-in to hold you.
Doing steel work has a tendency to
look more macho than climbing a tree but a tree is always a more frightening climb. . .
On steel I know my fall arrest gear will not fail, I know the tower will not fail (unless its old infrastructure), I know it’s O.K. to feel safe... But when in a tree, you never know the true health of the branch your tied into until you get into the tree and inspect it. I am always a tad leery when on a high climb (50+ feet) in a new tree.
A tree has NO safety rating, None, Nada!
I know I am not the first climber here to get up into a foreign tree and do a close inspection on the TIP and shudder upon realizing that is was partially hollow on its blind side.
As usual I digress, sorry. Back to the meat of the topic. . .As for the “
incredibly large pine” I spoke of earlier, it turns out that it measures at a not-so-incredible 60 feet tall. But it is still much too dense to attempt a roped climb.

Seems that tying-off
after you get to your working height is the only practical option on such a tree.
