A branch that ties into a straight 1.5" OD run at a right angle calls for the Ball Tee: pass-through axis, perpendicular outlet, and a decorative ball marking the joint, all in one cast piece. Stair rails pick it up where a landing branch joins; bar rails use it for a return. Because the three tube ends seat inside the ball, the straight lengths are cut to size and the fitting holds the branch angle. Available in polished brass, polished 304 stainless, or satin 304 stainless, with matching elbows, crosses, and single-outlet fittings in the same 1.5" ball line.
