For the 2" OD rail, the Ball El turns the 90° corner with the line's signature cast ball at the joint. It suits the head of a stair, the corner of a landing, or a balcony or bar rail, and it removes the need for a welded corner: both tube ends seat inside the ball, so the straight runs are cut to length while the fitting holds the corner. Polished brass gives a warm traditional rail; polished 304 stainless reads bright and modern; satin 304 stainless keeps glare down. The matching tees, crosses, and single-outlet fittings in the 2" ball line complete the system.
