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!!!!

Perfect

They hold very reliably for a long time. Much better than a single loop.

easier that using a screwdriver

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

Worked perfectly.

Somebody cannot count to 5 . raised a complaint with Amazon .au they told me they could not fix the problem, however they would give me a $10 voucher for my next purchase so , I was happy with that ,,,Till I tried to redeem my $10 on two different occasions and purchases ,and surpise it does not work , poor customer service.

Super hose clamps, fit perfectly on the hose and very easy to use.

Spring clamps are the way. For any hoses you move basically ever, you need something quick and easy like these. Cheaper in stores than Amazon most of the time, but they're very convenient.

Good size and function. Easy to tighten and loosen
