Amerimax 75-degree square corrugated B-side gutter elbow for K-style galvanized steel gutter systems. Use at the top and bottom of downspouts to direct stormwater off the eave and away from the foundation. The corrugated rib pattern adds rigidity at the bend so the elbow keeps its shape after years of expansion-contraction cycles, and the rust-resistant galvanized finish gives the part a long outdoor service life under flowing water.

• Fits 2" x 3" galvanized steel downspouts
• Bend angle: 75 degrees (the standard residential downspout offset)
• Fit type: B-side (Style B) - bends to the LEFT or RIGHT of the downspout face
• Material: 28-gauge galvanized steel
• Profile: Square corrugated to match K-style gutter components
• Female-female socket ends crimped for slip-fit into the downspout and matching elbow
• Compatible with all standard K-style galvanized 2" x 3" downspout systems
• Attach with sheet metal screws or 1/8" pop rivets (not included); seal joints with gutter sealant on top-of-downspout connections

Tip: The B-side (Style B) elbow is the SIDEWAYS bend - use it when you need to redirect the downspout left or right around an obstacle (window, gas meter, AC condenser, shrubbery) before continuing the run. The classic two-elbow downspout offset uses one B-side at the top of the downspout to step sideways, then an A-front at the bottom to redirect water away from the foundation - or two A-fronts back-to-back to step the downspout in toward the wall. Pair B-side elbows in opposing orientations to make a horizontal jog around a window.
