ABSTRACT:
A sliding door includes a frame comprising an elongated header member having a topwall, a backwall, an intermediate wall and a bottom wall. The bottom wall and intermediate wall are engageable with sliding door panel support rollers and the bottom wall and intermediate wall are interconnected by a separate support member to distribute door panel loads between such walls. A movable cover is attached to the header member by a hinge part including spaced apart flanges and projections co-operable with projections on the header member to support the cover in open and closed positions. The door operator is supported in the header member by a single angle-shaped frame member supporting a power supply, a controller and a door operator motor. An adjustable torsion bar assembly supports the door panel against sagging.
