Claim 11:
12. A corner joint comprising:
a first frame member defining a first longitudinal frame member axis;
a second frame member defining a second longitudinal frame member axis; and
a corner bracket coupling the first frame member and the second frame member to one another, such that the first frame member longitudinal axis and the second frame member longitudinal axis are substantially perpendicular with respect to one another, the corner bracket comprising:
a first retainer coupled to an end of the first frame member, the first retainer at least partially comprising at least one first material and defining a first longitudinal axis;
a second retainer coupled to the first retainer and defining a second longitudinal axis substantially perpendicular to the first longitudinal axis of the first retainer, the second retainer coupled to an end of the second frame member such that the first frame member and the second frame member are substantially perpendicular with respect to one another when respectively received by the first retainer and the second retainer, and the second retainer at least partially comprising the at least one first material;
a first exterior surface at least partially defined by the first retainer and at least partially comprising at least one second material, the first exterior surface comprising a first door panel interface configured to provide a first seal between the first exterior surface and an interior surface of a first door panel in a closed position, wherein the at least one first material is relatively more rigid than the at least one second material, and the at least one second material is relatively more elastic than the at least one first material; and
a second exterior surface at least partially defined by the second retainer and at least partially comprising the at least one second material, the second exterior surface comprising a second door panel interface configured to provide a second seal between the second exterior surface and an interior surface of a second door panel in a closed position, the first door panel interface and the second door panel interface substantially perpendicular with respect to one another;
wherein the first retainer comprises a first frame member interface configured to be coupled to the first frame member, and wherein the second retainer comprises a second frame member interface configured to be coupled to the second frame member; and
wherein the first frame member interface comprises a first aperture configured to receive a first fastener for coupling the first frame member to the first frame member interface, and wherein a sealing portion at least partially surrounds the first aperture and is configured to provide a first fastener seal between the first aperture and the first frame member.
