The Perpendicular Collar joins a second 2" OD railing tube to a primary run at a right angle, and its inside-fit design is what keeps the look clean: it slides into the end of the primary tube, leaving no collar profile on the outside, then accepts the perpendicular tube. Because it rotates a full 360° around the primary tube axis, you can orient that second run to any clock position and lock it there without re-cutting — a real time-saver when a run has to land just so. It fits.050" or.060" wall tubing and comes in polished brass, 304 stainless polished or satin, and 316 marine-grade stainless polished or satin for coastal, pool, and exterior settings. As the flagship 2" perpendicular fitting in the Universal Connectors line, it pairs with matching parts across the same family so a full run goes together cleanly.
