Join two 1.67" OD (42.4mm) handrail tubes into one continuous run. The 830-424 Flush Splice Connector fits inside the tube ends and locks them end-to-end inline, so a long corridor, a promenade, or a deck rail carries through as a single rail rather than separate lengths. It is sized for.080"-wall tubing built to the European DIN/EN standard, matching the heavier-wall 42.4mm material it splices. The 316 stainless finish, Polished or Satin, gives marine-grade corrosion resistance for coastal and exposed installations. Pair it with the matching 1.67" OD flush T and X fittings to keep a continuous handrail going through junctions and direction changes, all from the same 42.4mm family of parts.
