Abstract

An improved wire threader for threading one or more electrical wires into a flexible split conduit. Improved wire threader (10) includes an elongated first end member (15) defining a graspable member, a second end member (17), and a guide foot (19). The second end member (17) and guide foot (19) are axially aligned. The first end member (15) adjoins the second end member (17) and the guide foot (19) so as to form an obtuse angle with the second end member (17) and an acute angle with the guide foot (19). The first end member (15) and the second end member (17) are hollow elongated tubes, in fluid communication one with the other, each having an open end for electrical wire to travel through. A wire bundle is fed through the first end member (15) and extends out of the second end member (17). The guide foot (19) of the wire threader (10) is then placed into the open end of a flexible split conduit. The terminal end of the wire bundle is held stationary relative to the end of the conduit, wire threader 10 is pulled through the split conduit and additional wire is allowed to feed into first end member 15 of wire threader 10'.
