Duro Series™ HDPE Pin Insulators

HDPE Pin Insulator|


HDPE pin insulators are designed to support distribution and sub-transmission conductors, typically in a vertical orientation, by threading the insulator on to a pin installed on the crossarm or pole. Conducting cables are secured to pin insulators with the use of wire ties.
