Ducting elbows, sometimes referred to as bends, allow airflow direction change in a straight run of ductwork. Quick-Fit™ ductwork components from Nordfab Ducting have a rolled edge on the ends which provides easy connection to other components with use of a barrel-type clamp. A specially designed gasket inside the clamp seals the joint tightly. Simply and quickly clamp each piece together without welds, bolts, screws, flanges, special tools, or precise measurements. Once installed, you can quickly and easily take it apart for cleaning or to reconfigure for any floor plan changes. Ideal for most dust, mist, and fume collection applications. Adaptable to your existing ductwork. Reusable Quick-Fit ducting is easy to uninstall and relocate as your needs change. Quick-Fit ducting is easy to remove, clean, and reinstall without tools. Smooth, fully welded seams prevent leaks, snags, and possible “bug harbors”.
