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.
