4Pcs 3" Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps （65mm-89mm）

Works great.

Good clamps

Works great, just wish it had a Philips screw so that installation was easier. Flathead makes it a bit annoying, but still easy to use. Seems to hold very well and fit my AC duct perfectly.

They seem to be made well. I ordered them hoping to use them on my lawn vacuum hose. Although they are the proper size, they could be a little larger for a better fit. AI said that they would work for this, but I'm concerned about the strength of the clamps being enough to hold the hose in place. I haven't been able to try them for this yet, and will update after I have done so.

works great for providing secure counter pressure.

Great! Repeat customer who bought this in a differing sizes in past orders and the quality is still there!

We keep these as spares for exhaust clamps for our MerCruiser engine. Always a good idea to keep spares around. These were cheaper than the local hardware store and seem like great quality.

They did the job but the tightening mechanism is super cheesy and you can’t tighten to much or they jamb or slip. No more Chinese hardware for me it’s all junk
