Summary: The Wall Flange for 1-Inch OD Tubing (500/1) is a drilled-base wall flange from Lavi Industries that mounts 1-inch OD railing tubing to a wall. It is the smallest round wall flange in the 500 series, with a 2-inch base and a 7/8-inch projection from the wall. The base is pre-drilled, and a set screw in the neck locks the tube with hand tools. It is offered in solid polished brass or 304 stainless steel in polished or satin finishes. It is a light-duty flange for bar footrails, lobby accent handrails, and retail display rails. It matches the 1-inch tubing, end caps, and brackets in the same line, and the 500U/1 is the undrilled version. Ships from US inventory.
