Quick-Fit^® Long Radius 18 gauge Elbows have rolled ends for use with Quick-Fit Clamps, allowing quick assembly / disassembly and relocation. Learn more about the advantages of Quick-Fit ducting.

Available in 90°, 60°, 45°, and 30° with a radius of 2.5. Other CLRs available upon request. Standard 1.5 radius 18 gauge elbows are also available.

Heavier gauge construction may be the solution to reduce the frequency and cost of replacing worn-through elbows in high wear applications.

Available in Galvanized (as shown below) and 304SS or optional 316SS or carbon steel
Available with flanged ends in diameters up to 72", and other various end styles.
Elbows in even heavier gauges can be supplied in solid welded construction at an additional cost. Optional gauges standard 22 or 20, 16, 14, 12 and 10
