ABSTRACT:
A shim for use as a spacing or leveling device between two adjacent elements such as structural elements or the like. The shim comprises a planar structure of U-shaped configuration, having parallel leg portions joined by a base portion. A handle portion may also be provided, the handle portion being coplanar with and located centrally of the shim base portion and extending therefrom in a direction opposite that of the leg portions. A line of weakening may be located at the juncture of the handle portion and the base portion, rendering the handle readily removable after proper location of the shim. The leg portions may also be provided with one or more parallel, transverse lines of weakening so that segments of the leg portions may be broken off to adjust the length of the legs. The major or upper and lower surfaces of the shim are longitudinally striated, forming alternate, narrow, longitudinal grooves and ridges. As a result, two or more shims may be stacked to provide a shim assembly of greater thickness, with the alternate grooves and ridges of the stacked shims nesting to prevent lateral shifting of the stacked shims with respect to each other.
