    Arc-Resistant GPO3 Fiberglass Sheets and Strips

    Arc-Resistant GPO3 Fiberglass Square Tubes

    Image of Product. Front orientation. Fiberglass. Arc-Resistant GPO3 Fiberglass Square Tubes.
    Route and insulate wire using these square fiberglass tubes, which fit better along edges and around corners than round tubes. Use them for electrical applications in humid locations. They’re arc and track resistant, and better electrical insulators than FRP fiberglass. Made of fiberglass-reinforced polyester, they’re also known as polyester-grade industrial laminate.
