It works
This is a simple, low-cost strap for securing your expansion tank. I found it to be a little bit "wobbly" since the tank is much larger than the screw-down section of the clamp. It's not unsafe, however, and it does the job. If you typically like gold-plated, clean tools made in Germany this may not be the clamp for you. But if you just want to do the job in a secure, safe, economical way, this clamp works fine.
