Arc-Resistant GPO3 Fiberglass 90° Angles

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

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.

Arc-Resistant GPO3 Fiberglass Hat Channels

Color: Red
Temperature Range: -50° F to 265° F
Tensile Strength: 10,000-15,000 psi (Good)
Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
Hardness Rating: Barcol 50 (Hard)
For Use Outdoors: No
Specifications Met: UL 94 V-0

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.
