Abstract: An improved blocking member and vegetation barrier for the bottom of fences includes a riser portion that runs along one side of the fence. The riser is somewhat flexible and is securable to the fence in a manner that allows the installer to adjust the riser vertically relative to the fence or other portions of the riser, if necessary, and restrain it from any substantial vertical movement once secured. A ground covering member extends transversely from the lower part of the riser. Thus, the ground covering member can be placed directly on the ground even if the ground undulates relative to the fence bottom, and can be kept in that position once the riser is secured to the fence. The ground covering member can be resilient and create reactionary force if it is pressed against the ground. This can further assist in maintaining the blocking member and vegetation barrier in a fixed position relative the ground and the fence.

Abstract: An improved shim such as is used to wedge between door frames and walls in construction applications. The improved shim is made of a non-wood material which resists splintering, splitting, and compression. It also resists decay, rot and degradation over time. The shim is an elongated wedge-shape. It can include transverse slots, grooves, or scores which make it frangible at various locations along its length to size it to different lengths. The improved shim can be manufactured linked end-to-end and foldable into a compact stack.
