Abstract
A distortion-resistant wafer basket with an open top for insertion and removal of wafers and opposed side and end walls with the side walls having lower portions offset inwardly. An end wall is provided with a transverse indexing bar across its width and gussets joining opposing side walls with the indexing bar and spaced axially inwardly of the outer surface of the end wall. The gussets strengthen the end wall against distortion, and co-act with the offset side walls to stiffen the basket and to restrain twisting or bowing of the side walls.
