An electrical outlet cover having a pair of floating socket covers which are resiliently urged toward a first position wherein holes in the floating socket covers are not aligned with holes in the electrical outlet. The floating socket cover must be rotated from the first position to a second position wherein holes in the socket cover are aligned with holes in the cover and then pushed toward the socket for moving prongs on the plug into holes in the socket. While prongs on the plug are moving into holes on the socket the prongs are covered by the floating socket covers to prevent electrical shock resulting from touching prongs of a plug that is partially plugged into the electrical socket.

A tag holder () formed as a single stamping defines a singular body having a first tab (), a second tab (), and a third tab (). The second tab () is cut from the first tab () to define an aperture () in the first tab for receiving a hanger rod () of a product display, and then the second tab () is folded from the first tab () and aligned adjacent the third tab (). Protuberant lance portions () are formed from a surface () of the second tab () and extend toward the third tab (). A hang tag () is placed between the second tab () and the third tab (), with the aperture () in the first tab () aligned adjacent a hanger aperture () of the hang tag (), and then the second tab () is pushed toward the third tab () with the protuberant lance portions () extending through the hang tag () and against the third tab () to secure hang tag () to the tag holder ().

A size adjustable wrench socket is disclosed which has a plurality of jaws which are slidably engaged within a jaw guide for moving radially inward and outward relative to the jaw guide for fitting threaded fasteners of various sizes. A controller sleeve is configured for engaging upwardly extending protuberances of the jaws, such that rotation of the controller sleeve in various directions will moved the jaws inward and outward relative to the jaw guide. The jaws further include a plurality of upwardly extending teeth which are formed into planar shoulders of intermediate portions of the jaws. A latch member is provided having a planar surface from which a plurality of teeth downwardly extend for engaging the upwardly extending teeth of the planar shoulders of the intermediate portions of the jaws. The latch member is movable from a latched position to a released position. When disposed in the latched position, the teeth of the latch member engage the upwardly extending teeth of the jaws to latch the jaws in a fixed position relative to the jaw guide.
