  • Good Clamp
These are a lot easer to use than the one's without the thumb screw unless you are using a frill with a 1/4 bit to clamp it down. If you want something easy get some of the spring clips that you squeeze and you will never use anything ela=se

  • Thumb Screw Works great
Using in my shop for my new air filtration system, seal the saw dust in the system of bags. Just what I needed and fit the four inch hose connections.

I used these to connect bathroom vent exhaust in a tight attic space. The no tools thumbscrew was very helpful indeed.

  • If you need to clamp 4" clear flex dust hose these work
I bought other thumbnut type of clamp 4" they would not open far enough to use on the clear flex..these do..no sharp edges. Clamped tight.

  • Whish I would have found earlier
These work great. I have to move my hoses around constantly when I'm using my dust collector and these make it so much easier.
