Corridor and common-area turns on the European rail size use this radius corner: it rounds a 1.67" OD (42.4mm), .080"-wall handrail through a smooth 90° bend, keeping the hand moving continuously around the turn. A tube slides into each end for a flush joint. Made in 316 stainless, polished or satin, it resists salt air, chlorine, and wash-down, serving coastal commercial runs as readily as interiors. Both finishes carry the same corrosion resistance; choose polished for a mirror look or satin for a softer, low-glare surface. Note the OD: it won't interchange with 1", 1.5", or 2" tubing.
