Clamp Together Duct

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

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.

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.

While Clamp Together Duct is often the fastest, easiest and cheapest way to address dust/mist collection, it is often 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 Clamp Together Ductwork Works

US Duct's Clamp Together system utilizes a rolled lip that is formed on the end of all parts. The lips (think a small version of a 55-gallon barrel) of the mating parts are joined together with a gasketed, over-center clamp. The clamp pulls the ends together and envelopes them inside the sealing gasket. ALL parts and special hoods are available with rolled lips.

The system is available in galvanized and SS material. Standard gauges range from 18-24 gauge with the rolled lip formed directly onto the pipe — as an integral part of the pipe. The system is also available in gauges up to 10 gauge. In this configuration, a separate collar is used at the end of the pipe and fitted to the pipe the same as if it were a fitting.

Using the combination of a separate 11" long adjustable sleeve and/or the integral adjustable collar on each fitting, the US Duct Clamp Together system is infinitely adjustable. This feature along with the clamp enables the novice or the professional to reduce installation time by 70%.

The Benefits of Clamp Together Ductwork

Stainless Steel Duct Clamps

Our Duct Clamps are the key to a secure fit and are compatible with all brands.

Optional grounding brackets, welded to the clamp, are available for added conductivity assurance. Our grounding bracket is spot-welded to the clamp and holds two spring-loaded bolts against the metal surface of the duct to provide excellent conductivity throughout the system.

The US Duct stainless steel duct clamp is designed for repeatable and long term service. Our Universal Clamp design makes this clamp compatible with all brands of rolled-lip ducting. The over-center latch securely draws the special contoured band around the rolled lips of the components and seals them tightly. The clamp securely holds the duct but is ready for easy release for the next move or modification.

Infinitely Adjustable Ductwork

The use of an adjustable sleeve and the adjustable collar found on each fitting make CTD infinitely adjustable.

The heart of the clamp together system is the ability to cut the pipe and incorporate either an 11” adjustable sleeve or a standard fitting to receive that cut end of the pipe. Once the pipe is slid into the sleeve or the fitting to create the length needed, the standard clamp secures the pipe to the rolled lip of the sleeve or fitting by clamping it an O-ring.

With other types of connections, like spiral, flanged, or welded duct, the duct has to be cut exactly to fit. US Duct's Clamp Together Ducting can be infinitely adjusted, reused and reinstalled.

Quick and Easy to Install Duct

Install Clamp Together Duct 70% faster than flanged or spiral ductwork.

The number one reason tens of thousands of people have chosen Clamp Together Duct is the speed of installation. The adjustable sleeve, collar, and clamp greatly reduce installation time because there is no need to cut, bolt, weld, or rivet pipes together.

Both self-installers and contractors love the product because it is so simple. US Duct will provide you with simple, easy to follow "A" to "B" drawings of your specific system. Large or small systems are literally quick and easy.

The Best Alternative to Spiral Ductwork

Spiral ductwork is an often specified and commonly known duct pipe style. As the name implies, the duct is formed by spiraling and locking strips of metal together to form a continuous piece. This forming method enables the manufacturer to produce various lengths of duct in less time, creating a duct that is typically less expensive than duct formed by rolling sheets. Yet, when considering ductwork options for your customers and looking at the entirety of the project from design, manufacturing, shipping, installation and ongoing maintenance, spiral ductwork may not be the best solution.
