A frame assembly, for use in window and door applications configured to retain a panel, comprising a frame with a cover assembly and a support assembly having a track assembly, and a sill assembly and a header assembly both interconnected to a securing surface. The cover assembly is interconnected to the support assembly. The sill assembly comprises a roller member disposed in supporting relation to the track assembly, and the header assembly is disposed in supporting relation to the support assembly so that the frame is movable relative to both the header assembly and the sill assembly. At least a portion of the frame comprises a predetermined thickness and a predetermined width. The predetermined thickness is substantially less than the predetermined width so that both cooperatively and concurrently enhance viewing through the panel and the frame's stability.
