Abstract
A double sliding door arrangement cooperating with a double-wide door opening formed in an upright wall. A top header beam extends across and defines the upper extremity of the door opening. A pre-tensioning arrangement mounted on and extending lengthwise of the top header beam causes the header beam to be deflected upwardly into a shallow bowed shape. A support track is fixed to and extends lengthwise of the header beam and horizontally for predetermined distances along and rigidly fixed to the wall adjacent right and left sides of the door opening. Right and left slab doors are supported on and vertically suspended downwardly from said track in sidewardly co-planar relationship, and are movable along said track between closed and open positions. The doors in the closed position vertically load and downwardly deflect the header beam, whereby the initial upwardly bowed shape minimizes outward swinging between opposed inner edges of the doors when in the closed position.
