    Arc-Resistant GPO3 Fiberglass U-Channels

    Image of Product. Front orientation. Fiberglass. Arc-Resistant GPO3 Fiberglass U-Channels.
    These GPO3 fiberglass U-channels are often used for electrical applications in humid environments. They are arc and track resistant, plus they have better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're also called polyester-grade industrial laminate.

    Arc-Resistant GPO3 Fiberglass Hat Channels

    Image of Product. Front orientation. Fiberglass. Arc-Resistant GPO3 Fiberglass Hat Channels.
    Unlike similar U-channels, these GPO3 fiberglass hat channels have flanges for mounting to flat surfaces. Use them to route and insulate wire in humid environments. All of these hat channels are arc and track resistant. They also have better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're often called polyester-grade industrial laminate.
