Arc-Resistant GPO3 Fiberglass Sheets and Strips

Often used for electrical applications in humid environments, these GPO3 fiberglass sheets and strips are arc and track resistant. They offer better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're also called polyester-grade industrial laminate.

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.

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.
