Fulton 4 Inch Thumb Screw Key Adjustable 304 Stainless Steel Hose Clamps, Pipe Clamp, Worm Gear Clamps, Dryer Vent Clamp, Dust Collection, Automotive, RV Clamp 10 pack (4" Hose Clamps)

These have come in so handy and no tools needed

These are so much easier then the type that need a nut driver or screw driver. I am using them to hold together a 3D printed vent system. It doesn't require a lot of holding force but I've messed around with these and think they would be absolutely excellent on my electric clothes driver vent. The work very well, easy to tighten and loosen as needed. Highly recommend.

Generally a good product. If the clamp needs tightened a lot, yet still within the supposed operating range, the tail protrudes from the lead screw and collides with the thumb screw and becomes more difficult to tighten. Not terrible, just annoying. Once tightened everything is fine.

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

Easy clamps, just turn the knobs and watch the clamping power!

They are decent. The knobs come off very easily though

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’d give 5 stars but the thumb screw bumps the clamp when you turn it - otherwise they’re pretty nice.

Works as expected

I love these and can highly recommend them for anyone who hates slot screw drivers as much as I do!

Je les utilise pour tenir mes tuyaux d aspiration de 4 pouces de collecteur de poussiere dans mon atelier. Ca fonctionne mais la capacité de serrage n'est pas tres forte, la poignée etant petite. Ca fonctionne tout de meme bien si je brasse pas trop les tuyaux.

Very easy to use. Gearing mechanism is smooth.

I don't like the fact that as you tighten these and the the metal comes out where you twist,then it jams it up making it a pain to tighten!
