Abstract: An anchoring or locking device to enable snap-in installation of boxes for electrical wiring devices in which the snap-in locking device is separate from the box and may be used universally with all types of boxes. The locking device includes a mounting base plate and means to attach the base plate to the side walls or to the top and bottom walls of an electrical wiring device box, the base plate having resilient fingers or extensions projecting therefrom at an incline starting from a point rearward of the box on which the device is mounted and extending at an acute angle from such point in a direction toward the front portion of the box. The projecting fingers or extensions are compressed inwardly toward the base plate when the box on which the locking device is mounted is pushed into the hole provided for the box in the wall on which it is to be mounted.

Abstract: A plastic file sleeve and index card set for organized record retention and use, including a sleeve having two relatively wide end walls, two relatively narrow side walls, open at the top and bottom defining a sleeve cavity therein to receive index file cards as described. The index file cards include a body portion having a width corresponding to that of the sleeve cavity for insertion therein, and include a tabulating strip portion across the top of the card which is wider than the sleeve. The tabulating strip portion of the cards includes shoulder portions which project outwardly from each opposite end beyond the corresponding respective side edges of the body portion of the cards. The outwardly projecting shoulder portions of the cards rest against the top edge of the sleeve, thereby supporting the tabulating strip portion above the sleeve for visual examination without having to reach in the sleeve and withdraw cards for examination.
