Abstract
A closure assembly is provided including a track and a slidable and pivotable closure member. The closure member is engaged with the track proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft (for example at least two portions) (for example telescoping) which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member so that it may be safely and securely pivoted away from the closure assembly. Improvements to the abovementioned structure are also provided.
