Summary: The Cut Flange, Canopy, and Steel Insert for 2-inch OD Tubing (542/SET) is a post-base kit from Lavi Industries for 2-inch railing posts. It bundles three parts made to work together. The tube slides over the steel insert, the cut flange bolts down and carries the post, and the canopy hides the flange and bolts. The parts are 304-grade stainless steel in polished or satin, and the kit ships from US inventory. It works with .050-inch wall tubing in indoor and light-outdoor settings. It is the full base for a post at the head of a wide stair, along a balcony edge, or where an atrium rail starts. A spec sheet is available, and the 543/SET is the 1.5-inch version.

Cut Flange, Canopy, and Steel Insert for 2-inch OD Tubing
The 2" OD version of the flange kit pairs a steel insert and a structural cut flange with a canopy that covers the bolts — the post anchors to the floor and the base finishes cleanly in a single step. 304-grade stainless in polished or satin, suited to indoor and light-outdoor rails at the larger tube size.
