Rolled-Lip Clamp-Together Duct

The Quick-Connect, Quick-Assembly, No-Weld Ductwork

Laser-Welded Clamp-Together Ducting

Our Laser-Welded Clamp-Together Ducting (CTD) uses a gasketed over-center clamp that seals the rolled lip on the end of ALL clamp-fitting ductwork components.

Clamp-Together Ductwork Experts

At US Duct, we know more about Clamp-Together Ductwork than anyone. We provide ALL components and special fittings. The system is infinitely adjustable with adjustment capability built into EVERY fitting, unlike spiral ductwork, which takes FOREVER.

Clamp-Together Duct: Efficient and Versatile

While Clamp-Together Duct is often the fastest, easiest and cheapest way to address dust/mist collection, it is usually best used in conjunction with other connection methods as dictated by the application, or duct size. Our extensive knowledge will enable you to get the best solution—for the application AND the money.

How it works

Quack about quick and easy ductwork!

Our Clamp-Together System? It’s all about that smooth connection! Picture this: a rolled lip (kind of like a mini 55-gallon barrel rim) formed on the end of every part. These lips lock together using a gasketed over-center clamp that snugly seals the deal. Whether it’s pipe or special hoods, ALL parts are ready to roll with rolled lips.
Need options? We’ve got the materials to fit your bill! Choose from galvanized or stainless steel. Standard gauges run from 18-24, with the rolled lip directly formed onto the pipe itself. For those heavier-duty jobs (up to 10 gauge), we use a separate collar that fits like it was made for it—because it was.
The best part? The Clamp-Together system is as flexible as a duck landing on water. Thanks to a combo of our 11” adjustable sleeve and the integral adjustable collar on each fitting, this system is infinitely adjustable. Whether you’re a pro or waddling into ductwork for the first time, you’ll save up to 70% on installation time. Quack yeah, that’s efficiency!

Please let production know how good they made us look and that we are indebted to them as well. Derek and I are on the lookout for ways to reward everyone there for all the things you do for us, so stay tuned. I still can’t believe that all shipped same day! Also, Derek and I have been in Statesville installing this week.. The project is mounting 87 Eco Gates at individual drops. This would have been cake if we were installing into clamp together ducting. But, all the ducting was produced and installed by a local manufacturer using flanges. Much of it is out of shape, weld seams are large and make it so the flanges don’t fit, branches are at 30° and run tangentially to drops that are crooked or just not lined up, vanstones are lazily hammered out and some were even made sloppy on purpose to straighten out duct lines that were off by 10 or 15 degrees. Bottom line, it’s ugly and lazy and has made our job really difficult. We both worked for another clamp together duct company for a long time. Without these kinds of experiences, it would have been difficult to understand the value of a good manufacturer compared to a bad one. If anyone ever complains about a price increase, remember that you sell premium stuff with premium service

I highly recommend using clamp together ducting. It may cost a bit more than spiral, but the price difference is more than made up with the significant decrease in time needed to install. Overall, my projects have had lower install costs, plus far less downtime, using clamp together ducting.
