Abstract
Adhesive cleats having (1) adhesion in shear and (2) shear resistance of greater than about 40 pounds per square inch (2.80 kilograms per square centimeter) adhere a desiccative spacer to adjacent glass sheets to prevent spacer sag and/or spacer bow. A moisture-impervious sealant seals the airspace between the glass sheets to provide a multiple glazed unit.
