For the largest rail size, the Ball Tee provides the mid-run branch connection: a straight 2" OD rail passes through while a perpendicular outlet takes the branch, with the decorative cast ball at the joint. Typical placements include a stair rail with a landing branch and a bar rail with a return. The three tube ends seat inside the ball — the straight lengths are cut to size and the fitting holds the branch angle. Offered in polished brass, polished 304 stainless, or satin 304 stainless, it pairs with the matching elbows, crosses, and single-outlet fittings in the same 2" ball line.
