Each of the tabs is positioned adjacent to an opening larger than the tab to permit the tab to be compressed into the opening to provide a large degree of variability in the height of the tabs. The spacer also includes angled arms which engage with slots in the lower agitator portion to cause the spacer to rotate with the lower agitator portion.Field of SearchBottom drive | |
