What are the benefits of this design?

  •  It keeps the quick link from wearing out.
  •  Equally strong on both vertical walls and roofs.
  •  No edge of the U-Bolt thus can protect the quick line in the best possible way.
  • It’s fixed to the metal construction with not just one but more nuts, 4 nuts or 2 nuts, some of the nuts can loosen and the protection point will still remain safe.
