Flanged Long Radius Elbow 18ga

18 Gauge Long Radius Elbows (bends) allow airflow direction change in a line of dust collection ducting. 18 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.

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