On a 2" OD rail, the Side Outlet El combines the corner and the branch: the rail turns 90° while a third outlet takes a post or second rail at a right angle to the turn, all cast into one ball. The three tube ends seat inside the fitting, which holds every angle — the straight runs are simply cut to length. It serves a stair, a landing, or a bar rail return, in polished brass, polished 304 stainless, or satin 304 stainless, and pairs with the matching elbows, tees, and single-outlet fittings in the same 2" ball line.
