POWERTEC 70127 2-1/2 Inch Key Hose Clamp, Adjustable Stainless Steel Hose Clamps for Dust Collector and Dryer Vent Hose, Worm Gear Clamp, 5 pack

The main reason I bought these was because of the large thumb screw handles. The clamps work great because you can easily tighten them. I used them on several dust collection hoses, and I am very pleased. I have used Powertec products before and I am pleased with the quality. I will buy them again.

Does the job. Nice that you don't need a screw driver to install. Good clamping force. Would buy again.

Good clamp that is easy to turn and required no tools. It was somewhat hard to get it started so I dropped 1 star but they do work well and hold well and are easy to turn by hand

Already done a review for these. Am still very impressed with the way these clamps hold my ventilation and dust collection system together. They don't appear robust.... BUT THEY ARE!!!!

I use these on all my large wood shop tools that don't have a dedicated dust collection hose. Make dust collection much easier and efficient to use.

Perfect

A very good idea! I do think they are better than C-clamps. But, it takes a strong grip and hand strength to open it enough to be functional. I do think most men will love this. Women will too, but it is difficult

Work great! I thought I was only buying four for a great price. Imagine my surprise when I noticed there are 5. I used these for vacuum hoses.
