4Pcs 2.5" Adjustable 304 Stainless Steel Duct Clamps Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps （ 52mm-76mm, For 2.5" Hose)

I've used the two 3" clamps from this set. They seem to exhibit sufficient quality and so far have worked well to hold a heat shield on a crossover section of exhaust pipe. I put a bit of loctite on them as the previous ones loosened up, but I don't know if it was necessary. I'll update this if they rust, loosen, or fall apart.

Great value for my money, they are exactly as described and work perfectly. If I ever need more, I will order the same ones again.

These Clamps Are Excellent and the price is Fair. So many hardware items have almost doubled in Price since Covid, with the excuse that the supply chain costs have skyrocketed. The price of these Clamps have increased modestly, and I have used them for years, and am very satisfied. Would Highly Recommend !

Very nice clamps, unfortunately I didn’t get a chance to use them as the other components of my air suction system included clamps already (which was not very clear from the description. I will simply keep these on hand for future projects.

Very good Stainless steel clamps well made and well packaged

Hose clams that work well, easy to use, and does the job.

Used these clamps to connect my diesel heater vents to the hose. The heater only came with two clamps so I had to purchase extra because I split the flow of air between two hoses. These fit perfectly around the splitter and the vents. I am very pleased with this purchase.

Quality product, quick delivery.

Para mí deberían ser ma sgruesas ya que se ven muy frágiles

Very good stuff

Looked kind of small for 4", I gave it a try anyways, didn't my 4" hose sadly

These are exactly 3” without turning them off the first notch. Don’t buy these if your trying to attach 3” ducting. To small, maybe if your duct was 2.5” they would be ok. Total waste of time. Picture is of clamp just gripping first thread.

It says in the description and on the package that it is 4 inch. The clamps i got are probably for 3/8" hose.Now I have to figure out how to get a refund. $10 for 4 tiny clamps is a bit much.
