Abstract: A receptacle shroud and shroud removal tool coact to selectively restrict unauthorized access to a channel-bound electrical receptacle. The receptacle shroud comprises a channel-engaging wall and a receptacle cover. The receptacle cover comprises a tool-receiving aperture. The channel-engaging wall is sized and shaped for snug insertion in a pedestal-bounding, structure-receiving channel. The channel-engaging wall is retained by friction forces at shroud-to-channel interfacing. The shroud removal tool comprises a shroud-engaging end and a handle end. The shroud-engaging end is insertable through the tool-receiving aperture. The handle end enables a user to manually impart shroud-removing forces to the shroud-engaging end, which shroud-engaging end transfers the shroud-removing forces to the receptacle shroud. The shroud-removing forces are operable to remove the channel-engaging wall from the structure-receiving channel.

Abstract: The disclosed shank slot dial has two equi-diameter cylindrical members each having a like plurality of axial notches equally spaced around the circumferential surface of the member. Mating helical thread means formed on the members concentrically of the notched surfaces allow for relative rotation of the members, which adjustably varies the axial spacing between the surfaces for proper support of the shanks to be fixtured in the dial. Keying means in the form of an axial grove on one member and a radially movable set screw on the other member nonrotatably hold the members at selected axial spacings and with the notches longitudinally aligned. The shank components supported in the dial thereby are abutted only at their end sections in corresponding aligned pairs of notches and bridge across at their intermediate sections the spacing between the notched surfaces.
