A center mull for a double door assembly of a fixed inactive door and a movable active door, comprising:
- a mull base of non-wood material having a base end member and base sides extending substantially perpendicularly from opposite end edges of said base end member;
- attachment means for securing said base end member to the fixed door;
- abutment means, on said base end member, for engaging an edge of a movable door;
- a mull closure formed of sheet metal having a closure end member and closure sides extending substantially perpendicularly from opposite end edges of said closure end member;
- and
- first and second coupling means on free end edges of said base sides and said closure sides attaching said mull closure to said mull base, said coupling means including slots formed in one set of said sides which receive end portions of another set of said sides, said slots being formed in said closure sides and extending parallel to said closure sides, said slots being defined between first legs extending along said closure sides from first bends at said free ends of said closure sides and second legs extending parallel and spaced from said first legs from second bends at ends of said first legs remote from said first bends.
A multiple door assembly, comprising:
- an outer frame,
- a fixed, inactive door mounted in said frame,
- a movable, active door movably mounted in said frame between open and closed positions in said frame, said doors having abutting door edges;
- and
- a center mull extending across said frame adjacent to and parallel to said abutting door edges, said center mull including
- a mull base of non-wooden material having a base end member and base sides angularly extending from opposite end edges of said base end member,
- attachment means securing said base end member to said fixed door,
- a mull closure of non-wooden material having a closure end member and closure sides angularly extending from opposite end edges of said closure end member, and
- first and second coupling means on free end edges of said base sides and said closure sides attaching said mull closure to said mull base.
