ABSTRACT:
A patio door system uses a metal frame attached to a door jamb. A door panel to be installed in the frame includes a metal sill member and a metal jamb member. A pair of fixed door panel adapters is provided for insertion into the panel sill member when the panel is to be used as a fixed door panel. When the door panel is to be used as a sliding panel, a pair of wheel assemblies is installed in the panel sill member, thus permitting a single panel to be adapted as either a fixed panel or as a sliding panel.
