Shortly after these arrived I saw their potential for stringing together into a safety tether and attempted some home repairs at height. While assembly of the line was impressively efficient, these straps are apparently unrated for human suspension. Lesson learned.
They do work well for instrument and audio cables though.
These are high quality hook & loop straps which are much safer to use on cables compared to traditional cable ties. What is also useful is that they can be joined together to strap larger items. A little expensive in my opinion, though high quality and a large pack. You get what you pay for.
