Older 2" rails often turn at angles that no standard fitting matches. This adjustable elbow joins two 2" OD tubes and lets you set the angle on-site to meet the original geometry, with a sharp-angled flush joint — a practical alternative to a custom-fabricated bend when a restoration rail doesn't hit 90°, 135°, or 147°. It works on a single staircase feature or a longer run. It's made in 316 stainless, polished or satin, so it resists salt air and wash-down as readily as it suits an interior. One fit note: this fitting uses 2" OD.060" wall tubing, not the standard.050" wall of the fixed elbows — the thicker wall keeps the pivot rigid. It's the sharp-angled version; for a smooth curved bend, look at the radius adjustable elbow instead.
