Give a 1" OD brass railing a finished, decorative ending instead of a bare tube. The Ball Finial for 1-inch OD Tubing (00-604/1) presses in on a press-fit stem and sits a full polished brass ball above the rail — an ornamental terminus at the end of a small handrail, a retail or display surround, or a restored period rail where the ending is meant to be seen. Offered in polished brass for.050" wall tubing, it brings a warm, traditional finish to a brass railing system. It is purely cosmetic — it caps the tube end and adds the ornament, with no load or structural role — and pairs with the matching brass fittings in the same line so a single railing goes together from one family of parts.
