Summary: The Cut Flange, Canopy, and Steel Insert for 1.5-inch OD Tubing (543/SET) is a cut flange railing mounting kit from Lavi Industries that anchors a 1.5-inch post and finishes its base in one order. The tube slides over the steel insert, the cut flange bolts down as the structural base, and the canopy covers the flange and bolt heads. The parts are 304-grade stainless steel in polished or satin to match the rest of the rail. It works with .050-inch wall tubing and ships from US inventory. 304 stainless suits indoor and light-outdoor rails, not marine or coastal air. It is the whole base for a post at the foot of a stair, along a mezzanine, or at the start of an atrium rail. A spec sheet is available, and the 542/SET is the 2-inch version.
