Summary: The Floor Flange for 1.5-Inch OD Tubing (512/1H) is a polished brass floor flange from Lavi Industries for railing posts and balusters. A 4-inch base spreads the footprint on the floor, and a 1.5-inch socket receives the post so it stands square. It is a surface mount: the flange attaches with the wood screws provided, and the tube slips into the socket. It comes only in solid polished brass, which patinas naturally and polishes back when wanted. It is used on restored brass stair rails, lobby railings, and porch rails where posts repeat. It matches Lavi's brass cap rail, flush fittings, and ball fittings at 1.5 inches, and a spec sheet is available. Ships from US inventory.
