I don't believe that this rating reflects the QUALITY of the product. They appear to be well made. But they don't fit my application so I couldn't use them. Clamp size - inch to metric, extended to rest etc. I would consider a "number system" that you can use to match the pipe and clamp Since the clamps have such a low stretch range, they really MUST be the right size.
