QF Ball Joint
NordfabBall Joint to allow directional flexibility within QF ducting lines.
Nordfab QF Ball Joint allows up to 22° of movement off center. This makes the ducting more flexible as it can curve all different directions. Its use is similar to that of a QF elbow but an elbow has a set angle and direction whereas a ball joint has an angle from 0°-22°, depending on the application, and a 360° directional capability. It also connects very easily to QF ductwork with QF rolled ends.
