Review on Boao Adjustable Stainless Steel Clamps by Paul Sanchez

I have used adjustable air duct clamps for many years. I've never come across a clamp that doesn't have a little play to allow you to run it and slide it over the vent tube you're trying to secure. There was no more than 8 1/8 inches around. Usually start by attaching it to the vent pipe you wish to repair. 8" vent hole to tighten. I had to open the flexible hose all the way, then try to hold the two pieces close enough together with one hand, then try to guide it with the other hand. Once I was able to get it up and running "It took only one turn of the adjuster to tighten it. There's no room for error. Every adjustable clip I've ever used gives you over half an inch and sometimes more for you to slide onto the breather tube and can tighten. Not this one. I recommend looking for another product.
