The 2" Ball Single Outlet closes a run the traditional way: one tube end slips inside a decorative cast ball, replacing a raw cut with a rounded, finished detail at the end of a stair rail, a bar rail, or a post top. As an end fitting it has a single outlet and a single job. Polished brass suits a warm traditional rail; polished 304 stainless gives a bright modern finish; satin 304 stainless softens the look. The elbows, tees, and other ball fittings in the same 2" line let the whole run end in one family of parts.
