Where a rail turns a corner and a post or second rail meets the same point, the Ball Side Outlet El does both in one fitting: a 90° elbow plus a third outlet at a right angle to the turn. Three 1" OD tube ends seat into a single cast ball — a clean corner for a stair, a landing, or a bar rail return. The tube ends hide inside the ball, so you cut the straight runs and let the fitting hold all three angles. Cast in polished brass for traditional brass rails, it works with the matching elbows, tees, and single-outlet fittings in the same 1" ball line.
