Arc-Resistant GPO3 Fiberglass 90° Angles

- Color: Red
- Tensile Strength: See table
- Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
- Hardness: See table
- For Use Outdoors: No
- Specifications Met: UL 94 V-0
Because these GPO3 fiberglass 90° angles are arc and track resistant, they are often used for electrical applications in humid environments. They offer better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're also called polyester-grade industrial laminate.
