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.

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.

Strut Channel
Fiberglass channel is nonconductive with good resistance to chemicals and salt water. It's about half the weight of aluminum and has thicker walls than the other materials.
6'8" length channel is for use with beams spaced 6 ft. apart. The length allows 4" on each end to attach the channel to the beam.
Strut Channel Nuts
Serrated grooves securely grip the lip of the channel.
Fiberglass nuts are about half the weight of aluminum. They’re nonconductive and have good resistance to chemicals and salt water.
Sit-on-Top Strut Channel Washers
Add hardware to strut channel without having to hold the washer in place or reach inside the channel. Use with hex nuts to connect threaded rod.
Fiberglass washers are nonconductive. They also have good resistance to chemicals and salt water.
Corner Strut Channel Brackets
Fiberglass brackets are nonconductive with good resistance to chemicals and salt water. They're about half the weight of aluminum.
