Run a glass cap rail past the length of a single tube. The 830U-424 Channel Tubing Splice joins two 1.67" OD (42.4mm) channel-tubing sections end-to-end inline, so a long balcony perimeter or a multi-level stair run reads as one continuous rail rather than separate pieces. It keeps the U-channel groove aligned across the joint, so the glass infill carries straight through without a break. The splice is non-handed — it joins sections in a straight line with no orientation to sort out — and fits.060"-wall channel tubing in 316 Polished or Satin for marine-grade corrosion resistance. Pair it with the horizontal and vertical direction-change elbows in the same line to take a run around corners and up landings.
