Summary: The Channel Tubing Splice is a 316 stainless inline splice from Lavi Industries that joins two lengths of glass cap rail channel tubing in a straight line. Part number 47-830U/424 fits 1.67-inch OD channel tubing with a .060-inch wall and shows a 0.24-inch band at the joint. It keeps the U-channel aligned across the splice so the glass infill continues without a break. Threaded screw bosses hold the connection. It is offered in polished 316 stainless and satin 316 stainless. It extends a glass railing past the 16-foot length of a single A114U channel tube on long balconies, atrium edges, and multi-floor stairs. Ships from US inventory.

Channel Tubing Splice
Glass cap rails longer than a single length continue through the 47-830U/424 splice: it joins two 1.67" OD (42.4mm) channel-tubing sections end-to-end and carries the U-channel groove across the joint, so the glass infill continues uninterrupted. Fits .060"-wall channel tubing, in 316 Polished or Satin stainless steel.
