The Dual Auxiliary Arm is designed for use where a changeout of poles,crossarms or insulators is necessary; the standard Chance Epoxiglastools are lightweight and easily rigged. On regular construction, oralley arm construction, this tool can be used as a side arm. Movablewireholders can be spaced for minimum conductor travel from the crossarmto the temporary arm, yet the arm is long enough for use as a liftingarm with the use of three standard Chance Wiretongs. When the DualAuxiliary Arm is used on voltages above 15 kV, additional wireholderinsulation must be used; and when the arm is to support energizedconductors, during rain, or for a period of time when unforeseen raincould be possible, it is recommended that insulators be added to thewireholders for added protection against tracking on the arm. It is alsorecommended that when the arm is to be left up overnight or during aperiod of possible rain, the arm should be wiped down with a silicone-treated cloth.
