Turn the open end of a 1.67" OD Schedule 40 pipe handrail (1.5" nominal pipe) into a finished, decorative ending. The Ball Finial for 1.67-inch OD Tubing (47-604/424) presses in on a press-fit stem and sits a full round ball above the rail — an ornamental terminus for a waterfront rail, a pier or dock run, or an exterior pipe railing. Offered in 316 polished or satin stainless for.080" Schedule 40 wall pipe, it holds up to salt air, chlorine, and weather. Choose polished for a bright finish or satin for a softer look. It is purely cosmetic — it caps the pipe end with no structural or load role — and matches the rest of a 316 pipe-handrail run.
