    摘要: A non-contact voltage tester has a self-test feature so that when a switch clip of the tester is actuated, light and sound indicator devices are energized to give a single blink and beep, respectively, following which the tester is ready for probing for a voltage. The light and sound indicator devices also indicate the presence of a voltage when the switch is actuated and a voltage is detected at the probe tip of the tester.

    摘要: A plastic conduit bender comprises an integrally molded handle and head portion. A steel hook reinforcement is molded directly into the head portion to provide sufficient force for bending the conduit. Steel reinforcements can also be provided in a grip region of the handle. A plurality of vertical sight lines, indicating bend angles, are provided from an apex molded into the handle and extending to an arcuate shoe portion, allowing the user to gauge the approximate bend angle. A flat surface including rounded saddle portions for receiving the conduit is positioned on the handle to allow the conduit to be bent back or straightened, the rounded saddle contact surfaces preventing damage to the conduit as it is bent back.

    摘要: A bushing for a hole in a structural member includes a flange with an aperture there through. A plurality of tabs are hinged to the flange at locations around the aperture. During installation of the bushing, the plurality of tabs are inserted into the hole with the flange being located on one side of the structural member. The plurality of tabs then are flared outward on the opposite side of the structural member to prevent the bushing from being extracted from the hole. A plurality of latches retain the tabs in the flared position.

    摘要: A power hand drill has a subsurface object locator for detecting the presence of an object beneath a surface being probed with the locator. The drill has a housing with a flat accessory mounting surface having a pair of attachment tabs. The locator has a locator housing with a flat base and a pair of key hole slots engaged with the tabs for detachably mounting the locator housing to the accessory mounting surface of the drill housing. The locator includes sensing circuitry contained within the locator housing for detecting subsurface objects and has an object indicator mounted to the locator housing and connected to the sensing circuitry for indicating the presence of a subsurface object. A contoured surface on the locator housing provides a handrest for gripping when operating the drill.

    摘要: A tube bender angle indicator is attached to the handle of a manual tube bender and has a frame to which angle indicia are applied which define an apex through which a pointer is pivotally connected to the frame. A bubble level vial is secured to the pointer so as to indicate that the bend angle has been achieved which the pointer is pointing at when the bubble is in its horizontal reference position.
