Ducting Elbows to change direction of airflow designed for convenient assembly. 

Quick-Fit (QF) Duct Elbows, also referred to as bends, allow airflow direction change in a line of duct. They're available in 3"-24" diameters with 30°, 45°, 60°, and 90° angles, in galvanized or stainless steel. They are also available in regular or long radius. All elbows have QF rolled ends. 

Galvanized QF Elbows in diameters 3"-7" are press formed halves stitch welded together whereas diameters 8"-24" are segmented (gored). Stainless steel QF Elbows in diameters 3"-6" are tubed. Tubed elbows are air flow directional (collar on outside of tube for outlet and collar on inside of tube for inlet).
