g2 respectively a conventional tensioning strap or hold down strap s t includes a first end s1 conventionally connected in the manner illustrated in fig2 to the bed b while a second end s 2 is similarly conventionally connected to the bed b the second end s 2 of the strap s t can actually be a separate strap but irrespective of the particular construction thereof a conventional toggle mechanism tm applies tensioning forces to the strap s t and directly against each of the elongated members 20 of each of the pressure applying devices 20 in the manner clearly illustrated at fig1 and 2 of the drawings the pressure or force thus applied to the elongated members 21 of the pressure applying devices 20 is transferred through the pivot pins 71 to the pressure applying members 40 and through the layers of resilient material 80 and or 81 thereof centrally to the medial or central portions c1 c2 of the groups or stacks g1 g2 of glass edge stacked upon the bed b of the truck t the upper edges e3 e4 of the glass stacks g1 g2 project well above each of the pressure applying members 40 and the lower edges e1 e2 project well below the lowermost edges of the pressure applying members 40 thus the forces of the pressure applying members 40 are applied essentially.
