Finish the base of a floor-flanged post at the European 42.4mm (1.67" OD) standard. The canopy slides down over the tube and covers the flange, hiding the bolt heads and edge so the base looks clean where the post meets the floor. It's a cosmetic cover only, adds no load, and works on an existing 42.4mm floor flange or a new one. It comes in 316-grade polished or satin stainless steel for a modern look and marine-grade chloride resistance, so it holds up on an outdoor deck, along a pool edge, or in humid air. A spec sheet is available.
