Flanged Long Radius Elbow 14ga

Flanged Long Radius Elbow 14ga

14 Gauge Long Radius Elbows (bends) allow airflow direction change in a line of dust collection ducting. 14 gauge galvanized steel elbows are standard with Angle Flange (ANGFL) ends. Angle Flanges are attached loosely and retained via a vanstone lip.

All Nordfab Elbows are available in 90°, 60°, 45°, and 30° bends.

14 Gauge Elbows are supplied in solid-welded construction, providing a leak-free seam. Elimination of air leakage improves dust collection system efficiency, providing energy cost savings.

14 gauge steel construction provides extra durability for high wear applications.
