When a run built to the European rail size needs a true right angle rather than a curved bend, this is the fitting: a 90° flush elbow for 1.67" OD (42.4mm) handrail with a heavier .080" wall. A tube slides into each end and the joint finishes flush along the grip. Made in 316-grade stainless, polished or satin, it resists salt air, chlorine, and wash-down on exterior decks, marina rails, and waterfront balconies. Both finishes carry the same corrosion resistance — polished for a mirror look, satin for a softer surface. Note the OD won't interchange with 1.5" or 2" tubing.
