Quick Release & Adjustable Stainless Steel Thumb Screw Metal Strap Clamps for Dryer Vent Hose Connector and Plastic Vent Ducts - Easy Turn 3-4 1/2 inch Diameter (Pack of 2)

One of the clamps had a manufacturer's defect. When the problem was brought to the attention of the seller, they promptly issued a credit for the defective clamp. The other clamp is easy to twist & fasten. I will buy again in the future.

Great product worked perfect on my dryer

So nice to have this thumbscrew design! I use these on some ducting that I will want to move or remove periodically, and this makes it so easy - no screwdriver required. Not much more to say - a good product.

simple to use and did the job! needed to tighten my out hose from my dryer. also didn’t need a screwdriver to use!

This is a great idea poorly executed. The thumbscrews are plastic and molded over a small hex head screw that is used in the clamp. I have no muscle, and even my weak self was able to pop the thumscrews off and strip them out with much less than finger-tight pressure. Commence cursing while upside-down behind the dryer trying to clamp the vent hose. Worse, the hex nut is neither a standard Imperial or metric size. I learned this while dropping both kinds of sockets under the dryer, leading to more cursing.Ended up replacing them with standard screw-drive clamps and tossed them.Avoid.

Works great and can easily be used one handed

Fixed my dryer vent perfectly and was so easy to install. The thumb screw makes it so fast to put on. Couldnt be easier.

Unfortunately, the plastic thumb screw quickly became stripped despite the absence of excessive force. I was able to complete the tightening with a wrench, but the joy of my new dryer vent was diminished. Alas.
