6-Inch Hose Clamps Stainless Steel (Adjustable 5 1/2-6 1/3 Inch Diameter), Easy Turn Thumb Screw Metal Clamp, Ideal for Dryer and Plastic Vent Ducts, 5-Pack (Easy Turn Clamp)

I have put up and taken down ventilation tubing more times than I can count.More often than not I find myself in some akward position in a tight space where it's a pain in the neck to hold the tubing and tighten the screws on a clamp.When I first came across these I laughed and thought wow how didn't I think of that, I bought them immediately.I couldn't justify not buying them for the simple fact if the amount of time and energy they will undoubtedly save me in the future.They are the same price as the old screw in kind so the it really is a no brainier, when O run out of this pack I will absolutely buy another.MAKE LIFE EASIER AND BUY THEM!

The plastic knob is to wide!!! Had to struggle to get a full rotation from it!! i gave up on the second one! Very frustrating!! Just poor design! Did anyone try one of these?

The thumbscrew head will hit the band clamp in some applications. The extra metal band that comes through as you tighten it will stick up just enough to catch on the plastic, you can easily press it down and get the clamp tight, but it can be annoying for frequently installed and removed clamps.

Don't buy these terrible clamps the easy turn knob is too big so when you turn it it runs into the side of the clamp. You can get it started but getting it tight is impossible because the knob hits whatever your clamping to. Take a pair of wire cutters to the sides of the knob and it kinda works but I would just avoid them all together

This was not a good product for what I was going to use it for

easy to use

These are awesome for doing a 1 man job or if u don't want to have to use a screw driver most def recommend these

The thumb screws were broken on no less than 2 of the clamps and they don't easily clear the clamp ring. If you bend the clamp ring a bit to increase clearance, but you really shouldn't have to do that. The wing nuts fall off easily.
