I have used both types of
hose clamp to set up my dust collection system in my Hobby Shop. These work the best as they may be tightened or loosened quickly using a speed driver or screw driver. I have tried using the thumb screw version where I may want to do a quick change of the hose attachment but if the clamp is tight enough to hold the hose, it is difficult to loosen with your fingers. Using a pliers on thumb screws is awkward and slow. Roger H Strube, MD
