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.

Multipurpose Flame-Retardant Garolite G-10/FR4 Rectangular Tubes
 |
These rectangular tubes are flame retardant, machinable, and electrically insulating. They’re made of epoxy resin, making them good for use with printed circuit boards, insulating washers, and transformer components. With low moisture absorption, these tubes are often used as thermal insulators. Made with fiberglass fabric reinforcement, they’re strong and easier to machine than other glass cloth phenolics. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.
