Summary: The 90° Flush Radius Elbow for 1-Inch OD Tubing is a flush radius elbow from Lavi Industries that turns a 1-inch OD rail through a smooth 90-degree curve. Part number 40-731/1 fits .050-inch wall tubing and measures 1-7/8 inches on each leg. It is offered in polished brass, polished 304 stainless, and satin 304 stainless, and it ships from US inventory. The radius bend lets a hand slide around the corner without a break, and the sleeve inside the tube keeps the joint flush. It is the only 90-degree flush elbow Lavi makes at 1 inch. That makes it the standard corner for secondary handrails, pool ladder rails, and residential stairs. The 731/1H and 731/2 are the larger sizes.
Key specs: SKU=40-731/1 (40- standard prefix; base SKU 731 denotes 90° Flush Radius Elbow mechanism family, distinct from 730 135° Flush Elbow and from the sharp-angled 90° Flush Elbow subcluster); Tubing OD=1" (smallest OD in Lavi railing line; for residential, ADA secondary, spa, pool ladder applications); Materials / Finishes=3 finishes: Polished Brass, 304-Grade Polished Stainless Steel, 304-Grade Satin Stainless Steel (no 316SS; 1" OD applications rarely involve chloride exposure)
90° Flush Radius Elbow for 1-Inch OD Tubing
Turn a 1" OD handrail through a 90° corner with a smooth radius bend, so a hand keeps sliding around the turn. This is the smallest rail size Lavi carries — good for a secondary or lower ADA-height handrail, a residential stair, or a pool ladder rail. Three finishes: polished brass, 304 polished or satin stainless.
