Abstract
A "fish tape" for installing electrical conductors in conduits is provided with an anti-snagging device. The anti-snagging device comprises a spherical roller to forms the leading portion of the "fish tape" as it is fed into a conduit. The roller "rides over" discontinuities in the conduit that would otherwise interfere with the "fish tape" being fed through the conduit and then retracted therefrom.
