Abstract: Various embodiments of a voltage detection device and of related safety systems are provided. In various embodiments, the voltage detection device is configured to couple to safety headwear, such as via the one or more housing(s) of the voltage detection device coupling directly to the safety headwear or the voltage detection device coupling to an adaptor mounted to the hard hat.

Abstract: A shelf component including a generally flat, planar base and a pair of side panels, each side panel being coupled to the base on opposite sides thereof. Each side panel is pivotally coupled to said base such that each side panel is positionable generally on a first side of the base. Each side panel has an opening configured to receive a mounting hook therethrough. The shelf component further includes a pair of extension hooks coupled to at least one of the side panels or the base. Each extension hook is positionable on a second side of the base that is opposite the first side.

Abstract: A paper trimmer that includes a base having a paper cutting device pivotally attached to the base for providing a variable, user-determined cut angle. The cutting device further includes at least one guide rail; a blade carrier slidably mounted on the guide rail; at least one cutting blade retractably mounted within the blade carrier; a translucent paper holder positioned lengthwise beneath the guide rail, wherein one edge of the translucent paper holder is adjacent to the cutting blade; an illumination strip mounted on top of the translucent paper holder for illuminating the edge of the paper holder adjacent to the cutting blade; and a handle assembly mounted on the guide rail. The handle assembly further includes a first locking mechanism for holding the cutting device at a user-determined cut angle, and a second locking mechanism for raising or lowering the cutting device relative to the upper surface of the base.
