A bottom trim member secures a curved sheet element such as a windshield or the like on a surface. The bottom trim member includes a bottom trim extrusion having a connecting leg affixable to the curved sheet element and a gasket receiving leg. A gasket is disposed in engagement with the gasket receiving leg, where the gasket is shaped such that the bottom trim extrusion is positionable in multiple orientations relative to the surface and such that the gasket maintains a sealing engagement in any of the bottom trim extrusion multiple orientations. A securing member is affixable to the surface and cooperable with the bottom trim extrusion to secure the bottom trim extrusion to the surface in any one of the bottom trim extrusion multiple orientations.
