Summary: The Welded Floor Flange for 1.67-Inch OD Tubing (49-541/424) is a welded floor flange from Lavi Industries for posts in the European 42.4 mm size. Rather than a set-screw socket, it is a weld-on plate that the installer or fabricator welds to the tube. The post base then holds with no joint to work loose. The plate measures 3.94 inches across and .32 inch thick, and the Flange Canopy 540/424 slips over it to hide the plate and bolts. It is made in 316-grade satin stainless steel for marinas, promenades, and coastal terraces. On runs that mix floor and face mounting, it pairs with the Facia Mount WA102/424 in the same size. A spec sheet is available, and it ships from US inventory.

Welded Floor Flange for 1.67-Inch OD Tubing
European-size posts get the same welded joint: the fabricator welds a 1.67" OD (42.4mm) tube to this weld-on flange, so the joint never works loose in service. Weld the tube on, bolt it down, and continue the build. 316-grade satin stainless steel stands up outdoors and near water, year in and year out.
