Many Benefits of Nordfab's Quick-Fit Ductwork

• You Can Just Clamp It Together:Nordfab's Quick-Fit ductwork components 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. Installers simply and quickly clamp each piece together without any special tools. The telescoping Quick-Fit adjustable nipple eliminates precise measurements.
• It Is Easy & Fast To Install: Because Nordfab's ducting systems clamp together, no rivets, screws or welding are needed. This cuts installation and downtime by more than 45% compared to flanged ductwork installation.
• It's Re-useable: Quick-Fit ducting is easy to uninstall and relocate as your needs change.
• It's Easy To Clean: Quick-Fit ducting is easy to remove, clean, and re-install — without tools.
