ABSTRACT:
The present invention features a fish constructed of assembled sections of fiberglass rods, one-quarter inch in diameter. Each length of fish section is provided with a female connection on opposite distal ends. A connector having a male end at both sides is also provided so that any length of fish can be assembled to suit the job requirement. It has been found that assembled six foot sections of fiberglass having a one-quarter inch diameter will provide the best flexibility over a wide range of lengths. Each six foot section is of a length that is easily stored, transported and handled by a skilled electrician. Each male and female connection is preferably made of steel or other metal to provide strength at the joints of the fiberglass sections.
