  • Rolled Lip Laser Welded Clamp Together Duct

    We know you'll fall in love with Clamp Together Duct!

    Rolled Lip Clamp Together System utilizes a rolled lip that is formed on the end of all parts. The lips (think small version of a 55 gal 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. The duct is available in galvanized or SS and in most gauges (depending upon diameter). Using the combination of a separate 11" long adjustable sleeve and/or the integral adjustable collar on each fitting, the 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%.

An adjustable sleeve pipe allows for infinite adjustments in the field. The components (pipe, branches, elbows, etc.) are offered in a ‘light’ and ‘heavy’ standard gauges ranging from 22-18.
