GPO channels and angles are similar in material construction to the Grade UTR flame and track resistant laminates. A small GPO Channelsamount of continuous glass roving is added to aid in pultrusion processing. These high-strength pultruded shapes have a wide variety of uses in both electrical and non-electrical applications. They are arc and track resistant and have a UL94 rating of V0. These versatile GPO-3 shapes are easily machined to fit a variety of needs in electrical design and construction. They are readily available in a variety of profile sizes and lengths.
