Abstract

A spacer stock and/or spacer frame having a pair of spaced outer legs joined by a base has a strengthening member integral with the base or an insert between the legs to reduce the degree of torsional twist of the spacer stock and/or spacer frame. In one embodiment during the forming of the spacer stock a "T" shaped member is formed integral with the base to reduce the degree of torsional twist.
