Arc-Resistant GPO3 Fiberglass U-Channels

- Color: Red
- Tensile Strength: 10,000-15,000 psi (Good)
- Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
- Hardness: See table
- For Use Outdoors: No
- Specifications Met: UL 94 V-0
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.
