Abstract
An extension platform for a beam balance scale and the combination of such a platform with a beam balance scale. The extension platform includes a generally planar upper surface and a lower surface having a grid of reinforcing ribs formed thereon subdividing the lower surface into a plurality of compartments. The lower surface is given a seating projection which depends therefrom and is configured and dimensioned to snap in place over the peripheral rim of the load-receiving platform of a beam balance scale of preselected size. The beam balance scale is thus rendered more accurate when used in the weighing of fibrous low bulk density materials.
