For a 2" OD handrail that changes direction at a wide 135° interior angle, this flush elbow makes the turn without a welded corner. A tube slides into each end and the joint sits flush, so nothing sticks out along the grip line. It's the corner for landing turns and angled intersections on a heavier 2" rail — a single large staircase or a longer run both. The finish range is wide: polished brass for a warm traditional or restoration rail, 304 stainless polished or satin for a modern interior, and 316 stainless polished or satin where salt or chlorine is present, like a beachfront deck or a pool surround. It fits.050" wall tubing and pairs with the matching 2" flush fittings so the whole rail comes from one family of parts.
