Abstract: A plastic shim or other workpiece useful in the construction industry. The shim or workpiece is an elongated tapered hard plastic body incorporating qualities of a shim lacking in wooden shims. Each shim has transverse break lines so that segments can be broken off to adjust its length. For handling, a plurality of such shims are molded in a sheet with adjacent shims being spaced along their thinner sections but separably joined by longitudinal, break lines extending along their thicker sections, whereby the shims can be detached from the sheet either individually or in multiples. The shims may have pockets defining nailing portions of reduced thickness which minimize the grasp of nails by the shim and allow removal of nails without damage to the shim or adjacent wood and etching to avoid uncontrolled slippage.

Abstract: A plastic shim or other work piece useful in the construction industry is provided and is an elongated tapered hard plastic body incorporating qualities of a shim lacking in wooden shims. Each shim has transverse breakable lines so that segments can be broken off to adjust its length. For handling, a plurality of such shims are molded in a sheet with adjacent shims being spaced along their thinner sections but separably joined by longitudinal, manually breakable lines extending along their thicker sections, whereby the shims can be detached from the sheet either individually or in multiples. The shims have pockets defining nailing portions of reduced thickness which minimize the grasp of nails by the shim and allow removal of nails without damage to the shim or adjacent wood and etching to avoid uncontrolled slippage.

Abstract: A locking device for use with an electrical plug having a pair of spaced, parallel tines each of which has an aperture located at a selected end and wherein the apertures are positioned in spaced axial alignment with each other and the locking device includes a housing having an opening which is adapted to receive and pass the ends of the tines, a releasable locking member located within the housing and adjacent to the opening and which includes an elongated member having a circumferentially extending continuous slot formed around the periphery thereof at a selected location and which has a geometrical dimension which is smaller than the geometrical dimension of the outer surface of the elongated member and wherein the elongated member is slideably mounted within the housing for linear movement relative to the ends of the tines between a first position where the slot is remote from the apertures in the tines and a second position where the slot is located between the ends of the tines containing the apertures
