Abstract: An improved plastic hinge shim or work piece that allows for quick alignment of a door is claimed. The hinge shim is an elongated tapered hard plastic body wherein each hinge shim has transverse break lines so that segments can be broken off. Additionally, the hinge shims are molded in a sheet of a plurality of shims such that they can be folded to form a thicker hinge shim as required for application. The slots provided for the hinge mounting screws permit the hinge shim(s) to be moved further into the cavity or out toward the hinge pin to provide for finer adjustment. These hinge shims can easily slip into the cavity under the hinge without the need for trimming. Moreover, the center slot for the hinge screw is open to the thin edge to permit the hinge shim to be inserted into the cavity without removing the center screw.
