POWERTEC 70247 1-1/2 Inch Key Hose Clamps, Adjustable Stainless Steel Thumb Screw Hose Clamps for Dust Collection, PVC Tubing, Pipe Clamp, Worm Gear Clamp, 5 pack

These are super handy because you don't need a screwdriver to tighten. Just put them on the pool pump connections, so I don't know the longevity, but so far so good.

Great functionality. I actually use this to secure my beach umbrella shade tilt hinge that does not stay locked straight since it was a cheaper plastic. I just leave it on stem and then tighten it into place when want to lock hinge in straight position. Presto!

These are fantastic. I replaced all my pool ones with these. No screwdriver needed! I have some with the plain metal key, but those are cheap and crappy. These are rock stars!

Did have one of the clamps snap apart when I tried to tighten, but overall they worked pretty good.

Quedé muy conforme con el producto!! Ampliamente satisfecho!!

I bought the wrong size (too small for my project) but am keepimg because I like the function/design. Nice not having to use a screwdriver

These are great for being able to leave the tools in the garage. But a few of them are getting hard to tighten. They’re all smooth loosening, but maybe there’s some junk in the crank? I’m going to try putting some lube in there.

I love these thumb screw clamps and wish I had an entire cabinet of them. I used this particular size on my Intex 18' round pool on the hose connections. So much better than having to putz around with the traditional kind. Quick and easy to adjust, they just make life a lot simpler!
