4Pcs 6" Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps（141mm-165mm）

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

Sturdy and strong, as they should be!

Seems to be decent clamps but the bolt size is not 5/16 like all other manufacturers. Might not be an issue for some but I would prefer using one size nut driver for all my clamps

great

Clamps work great. A bit lighter duty than more common options. Quality appears to be good.

Good size for 7" duct and they tightened without stripping.

muy resistentes, buen material

Very tight secure clamp! Does exactly what it's supposed to do.
