ABSTRACT:
A theft resisting device for use as part of an electric watthour meter includes a moveable slide bar positioned in a housing within the base plate of the meter. The slide bar is normally retracted, but when unauthorized removal of the meter from its socket occurs, the bar extends thereby preventing reinstallation of the meter in the socket in any position. Locking means engages the slide bar to prevent retraction of the bar. An access aperture to the housing permits a tool to be inserted to reset the locking means and permit slide bar retraction.
