Long Shank Insulator Pin is the framework that holds and sustains the overhead electricity wires. Crossarms are held together and kept from shifting by the use of a pin. This is present on both crossarms as well as one crossarm. This can be strengthened and given increased vibration resistance by linking them together.Long Shank Insulator Pin connects a cross arm with an insulator mounted on it or two cross arms. Additionally, it is included in a single crossarm to link them together.
