ISPINNER 2pcs 4 Inch Key-Type 304 Stainless Steel Worm Gear Hose Clamps, Adjustable Size Range 91-114mm Clamps for Dryer Vent, Dust Collector and Automotive

Awesome construction, actually grips the hoses well (dryer vent 4") and doesn't break apart like the cheap Chinese ones you get at home depot. Would strongly recommend and the ease of install with the wing nuts is clever and well worth the extra $1 each you would spend at home depot for terrible ring clamps that bearly clamp and break. 10/10

These way out perform the other clamp styles. Easy to install and have a “biting” design with each turn, so you’ll really get a tight compression and no screwdriver needed. A MUST for tight spaces when you may only be able to get one hand back there to install.

Saw this clamp on a youtube video, and got it to try since I was redoing my dryer vent hose and pipes with all new materials. The clamp itself is well made, much better than the cheap aluminum ones that come in those dryer vent hose kits.For the vent pipe side, it was easy to attach the clamp. It does take a bunch of twists to fully tighten the clamp. The traditional philips screw clamps are faster to install when you use an electric screw drill. But it is a one-time install, so it's not that bad.For the dryer side, my LG dryer has a short pipe but it is in a recessed area. The clamp can't fit exactly where it should go because the thumb screw sticks out. Unlike the philips screw types.. So I have the clamp mounted at an angle so there is space to turn the thumb screw. It works, but not ideal.If you want better quality clamps, I'd suggest getting one with the regular philips screws. Those are faster to install, and easy enough to finish with a screwdriver.

Worked well. I really like the fact that I didn't need a screw driver to tighten the clamp. Much easier this way.

Those is a great product for easy tightening.Make sure you have clearance for the wings, however. Some tight spaces (like attaching directly to the dryer) will not give you enough space. However, they were great for attaching vent hose to the wall and joints of exhaust hose.

Easy to use and did the job

I had my dryer vents cleaned. But when we tried to re-use the previous clamp it wasn’t screwing tight. These looked like an easy choice. No screw driver needed. This clamp was super easy to use. And my other one was fine so I didn’t have to use both clamps.I highly recommend this clamp for dryer hose applications. And it doesn’t cost a fortune!

PERFECT FOR MY CLOTHES DRYER HOSE. It is as advertised and worked very nicely on my dryer vents and enabled me to get rid of the horrid rusty spring steel clamps that came with the vent duct. Nice shiny stainless steel with attractive and well molded wingnuts.BUT:I wouldn't even be writing this review if the spec sheet didn't designate this clamp as suitable for automotive use. For auto air or ram ducting - maybe. But I wouldn't personally use them in that sense.The worm gear is loosely fitted in a very thin housing and the plastic wingnut bottoms out on the tension band when sufficient torque is applied. I have not personally tried this product in an automotive setting because I have enough common sense and experience in that area that I wouldn't even try to use this on a 4" vehicle hose clamping application, other than, as mentioned above, on low pressure non-critical ductwork.When you get into automotive pressure applications above 3" diameter, you are usually talking about commercial uses, such as diesel engines, trucks and tractors. It is my OPINION and my OPINION ONLYthat these 4" hand-tightened clamps just wouldn't cut it because of the narrow width of the band and the weakness of the tightening mechanism. I also believe the plastic wing nuts would break off if one were to torque the band to proper spec necessary to secure a 4" engine hose. In many 4" hose applications it is doubtful that the small size of the wingnuts would allow you to achieve proper torque before the strength of your hand reaches its limits. So, then some Bozo will show you how it's done using a set of plyers which would definitely snap the plastic wings. Then where will you be? You'll be U.S.C.OPINION and Free advice-for what it's worth.
