A mounting assembly for mounting a movable door panel (20) at an opening of an enclosure (12) between opposite walls (16, 18) of the enclosure (12) having a horizontal header rail (44) and an adjustable header expansion assembly (52), characterized by:
said horizontal header rail (44) mountable at the opening above the door panel (20);
said adjustable header expansion assembly (52) having a shaft (64) extending longitudinally relative to the rail (44) and a nut (62) in threaded engagement with the shaft (64), said nut (62) disposed within the header rail (44) such that the shaft (64) and nut (62) can be rotated relative to one another to expand the header expansion assembly (52) and increase the length of the header rail (44) for mounting the header rail (44) to the enclosure (12) by opposing compressive forces acting on the walls (16, 18); and
a curb rail (86) having two rails (86, 88) positioned at opposite ends of a curb expansion assembly (96) for mounting the curb rail (86) to the enclosure (12) beneath the header rail (44), wherein the curb expansion assembly (96) has a curb shaft (98) and a curb nut (100) in threaded engagement and coupled to the curb rail (86). |
