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.

High-Temperature High-Strength SG-200 Fiberglass

SG-200 fiberglass withstands temperatures up to 410° F—higher than any of our other fiberglass raw materials. It’s also stronger than FRP fiberglass and easy to machine. You can even use it in punching machines to create a variety of shapes and parts.
