QF Ball Joint

Installed in ducting as part of a dust collection system, the Nordfab QF® Ball Joint allows up to 22° of movement off-center. The swivel movement allows flexibility in the duct, allowing it to rotate in all directions. The ball joint’s use is similar to that of a QF Elbow but an Elbow has a set angle and direction whereas a ball joint has 360° directional capability and an angle from 0°-22°, depending on the application.

Odd sizes available with 6 week lead time.

• Available in Galvanized (as shown below)
• Available with flanged ends in diameters up to 14", and other various end types

Contact Nordfab or your local Nordfab dealer for assistance with larger sizes and end type options.
