1. An extruded channel frame member forming a core insert for a door structure, comprising a substantially rectangular frame member having the facing portion thereof projecting outwardly of said door structure, the bottom segment of said frame member having a plurality of vertically spaced tiers

1. An extruded channel frame member forming a core insert for a door structure, comprising a substantially rectangular frame member having the facing portion thereof projecting outwardly of said door structure, the bottom segment of said frame member having a plurality of vertically spaced tiers therein extending inwardly of said frame from the inner side of said facing portion, said tiers having their inner edge portions and their end portions in stepped relation, a sash receiving track formed between said facing portion and the inner edge of the uppermost of said tiers, sash receiving tracks formed within the vertical spacing between adjacent stepped pairs of said edge portions, vertical drain passages formed between said stepped end portions of said tiers and the respective adjacent vertical end walls of said frame member, an open bottom channel depending from the lowermost of said tiers, and drainage holes to the atmosphere through said channels formed between the ends of said last mentioned tier and said adjacent end walls. 2. The structure of claim 1, including sash receiving tracks in the side and top segments of said frame corresponding to said sash tracks formed in said bottom segment. 3. The structure of claim 1, including upwardly angled flanges formed along said inner edge portions of said tiers. 4. The structure of claim 1, wherein said tiers have portions angled downwardly adjacent said inner side of said facing portion. 5. The structure of claim 1, wherein said open bottom channel depends from said facing portion projecting outwardly of said door structure. 6. The structure of claim 1, wherein said drainage holes are formed in said projecting facing portion of said frame member whereby drainage from said drain holes falls clear of the adjacent door structure. 7. The structure of claim 1, wherein an upward projection of said facing portion forms the outer wall of said first mentioned sash channel. 8. An extruded channel frame member forming a core insert for a door structure, comprising a bottom frame segment having an outer wall portion projecting outwardly of said door structure, a plurality of tiers vertically spaced cantilevered inwardly of said frame segment from said outer wall portion forming drain channels, said tiers having successively greater widths and having upwardly flanged inner edge portions, the lowermost of said tiers having a portion thereof spaced from said projecting portion forming a bottom wall, the uppermost of said tiers and a corresponding upward projection of said outer wall portion forming a track to receive a sash member, a sash track formed in the vertical space between the inner flanged edge of the uppermost of said tiers and the directly underlying of said tiers, a sash track formed in the vertical space between the inner flanged edge portions of said underlying of said tiers and of the lowermost of said tiers, said frame segment having its ends mitre cut to have the same in a stepped relation, the lowermost of said tiers having its respective end portions set back from the adjacent sidewalls of said frame member forming drain holes therebetween, and said last mentioned tier having an open bottom channel thereunder through which said drain holes discharge to the atmosphere.
