ABSTRACT:
An electrical installation tool for use in electrical wire installations in areas of varying and unknown configuration comprising of a movable cable with a handle end and an adjustable fish wire end. The adjustable fish wire end is provided in the form of a bundle of flexible loops. Each of the flexible loops has an outer end that is secured to the cable fish wire end with the other end of each of the flexible loops being effectively held together at an intermediate point. The loops flare outwardly in a convex bundle, whereby the cable fish end can be moved back and forth. This movement has the effect of varying the distance between the cable fish wire end and the intermediate point, thereby to vary the flaring of the loop bundle to allow passage of the loop bundle or expansion or contraction of the loop bundle, as desired, in an area of varying or unknown configuration.
