3. A sliding screen door frame in accordance with claim 2, characterized in that said bottom channel track means comprises a vertically disposed and elongated flange connected to or otherwise integral with said second edge of said bottom channel web means, said flange having an upper edge operating as a bottom track for said screen door so as to provide said stabilized path.

4. A sliding screen door frame in accordance with claim 2, characterized in that said vertically disposed flange of said bottom channel connecting means comprises a bottom mount having spaced apart apertures extending horizontally therethrough, said spaced apart apertures adapted to receive attachment means for attaching said bottom mount to said stationary and vertical surface surrounding said entry door.

5. A sliding screen door frame in accordance with claim 4, characterized in that said horizontally disposed and elongated bottom web has a width between said first opposing edge and said second opposing edge which causes said bottom door track to be centered approximately 1.625 inches away from said stationary and vertical surface surrounding said entry door.

6. A sliding screen door frame in accordance with claim 5, characterized in that:

said bottom track extends upwardly approximately 1.0 inches above said horizontally disposed and elongated bottom web; and

said bottom channel mount extends approximately 1.0 inches down from or below said horizontally disposed and elongated bottom web.

7. A sliding screen door frame in accordance with claim 4, characterized in that a length of said bottom channel track is at least twice the width of said screen door to be used with said sliding screen door frame.

8. A sliding screen door frame in accordance with claim 1, characterized in that:

said top channel web means comprises a horizontally disposed and elongated top web having a first opposing edge and a second opposing edge extending longitudinally along the elongated configuration of said top web; and

said top channel connecting means comprises a vertically disposed flange connected to or integral with said first opposing edge of said top web.

9. A sliding screen door frame in accordance with claim 8, characterized in that said top channel track means comprises a pair of vertically disposed and elongated flanges connected to or otherwise integral with said top web and extending downwardly from said top web at or adjacent to said second opposing edge of said top web.

10. A sliding screen door frame in accordance with claim 9, characterized in that said pair of vertically disposed and elongated flanges of said top channel track means form a downwardly opening U-shaped channel portion, said U-shaped channel portion adapted to receive said top portion of said screen door in said sliding engagement, so as to provide said path for movement of said screen door between said open and said closed positions.

11. A sliding screen door frame in accordance with claim 10, characterized in that a depth of said U-shaped channel of said top door track is sufficient so as to accommodate over-insertion of said screen door into said U-shaped channel of said top door track.

12. A sliding screen door frame in accordance with claim 10, characterized in that said top channel track means further comprises a top channel door rail extending downwardly from a bottom surface of said top channel web and having a vertically disposed and elongated configuration, with said top door rail being substantially centered between said pair of flanges forming said U-shaped channel portion;

and

when said screen door is installed on said sliding screen door frame, said top portion of said screen door is in sliding engagement with said top door rail, so as to provide said path for movement of said screen door between said open and closed positions.

13. A sliding screen door frame in accordance with claim 10, characterized in that said vertically disposed flange of said top channel connecting means extends upwardly from said first edge of said top web, and comprises a top mount having spaced apart apertures extending horizontally therethrough, said spaced apart apertures adapted to receive attachment means for attaching said top mount to said stationary and vertical surface surrounding said entry door.
