Corridor T-intersections on the European rail size — a rail meeting a branch at a door entrance or a public-space transition — run through this fitting: a three-outlet flush "T" that branches 1.67" OD (42.4mm) handrail at 90°. Tubes slide into each outlet for flush joints, so nothing protrudes along the grip. The 1.67" size carries a heavier .080" wall. Made in 316 stainless, polished or satin, it resists salt air, chlorine, and wash-down; both finishes carry the same corrosion resistance, so the choice is visual. It is the branching counterpart to the radius corner at the same size — a run with both corners and branches uses each. Note the OD won't interchange with 1.5" or 2" tubing.
