Elbows: Tubed

KB Duct Tubed Elbows are standard, galvanized 16 gauge in 3” and 4” diameters and 14 gauge in 5”, 6” and 8” diameters. Our tubed elbows are the only offering of stainless in the smaller diameters of 6” and below and all stainless are 14 gauge. They have a completely smooth interior and are typically used in paper, fiber and heavy to medium abrasive applications.

Standard is 1.5 CLR, but 2.5 CLR are available. The tubed elbows have a 2” tangent on both ends, which will add a total of 4” of straight to each end when the rolled lip KB collar is added. The rolled lip of the collar can be attached flush with the raw end of the elbow for added protection in abrasive  applications.

As an option, 11 gauge is available in all diameters offered in galvanized and stainless. Custom bends and CLR (up to 4xD for some diameters) are available, upon request. Call for additional information.
