  • Easy to install
Easy to install, seem very sturdy

  • Perfect size for 4” flex
You have to pick your spots due to the width of the thumbscrew you can’t put the band right against the blastgate

  • Used in location where I only could get 1 hand in. Made install supper easy.
I used this in an attic where I could not use 2 hands to hold a screwdriver and hold the clamp. Made the install a breeze.

  • A bit too small for what I needed.
I didn't end up using these since they were a bit too small for what I wanted to use it for. The tab is made of a strong plastic material. I tried removing one to see if I could use it without the tab. You can pry the tab off by gently rocking it back and forth using some pliers. This exposes a 4mm hex. you are still able to use the plastic tab and store it for later use. ... show more

  • Great for dust collection hoses.
The thumb screw ends are large enough to tighten sufficiently without trouble. I’ve had these now for a couple of years. No problems at all. My table saw came with the same type of clamp for the smaller hoses. Would recommend.

  • They work, but I was sent an opened package...
These are medium duty and work as such. Only complaint is that I was sent a pack that somebody had obviously opened and returned. While they appear unused, they should clearly have been labeled as an "open box" item and perhaps had the price adjusted accordingly.

  • Much better than using a screwdriver
I bought these hose clamps for the dust collection system in my woodworking shop. The current clamps use various bolt sizes with a Phillips screw indentation. I get tired of finding the right socket to tighten them. This uses the plastic finger grips to tighten the clamps. So far they have been durable and easy to use. ... show more

  • Very narrow width!
Smaller than I've ever seen. Very narrow plus had to use small vice grips to turn. Won't buy again.
