Make a clean 90° turn in a 1" OD round brass rail without welding a corner. The Ball El joins two tube ends inside one cast fitting with a decorative ball at the joint — the finished look you want wherever a rail changes direction: the top of a staircase, the corner of a landing, or a deck or balcony rail. The tube ends seat inside the ball, so you cut the straight runs and let the fitting hold the corner — no exact corner measuring. Cast in polished brass for a warm, traditional rail or a brass restoration, it pairs with the matching tees, elbows, and single-outlet fittings in the same 1" ball line so a whole run goes together from one family of parts.
