Multipurpose Flame-Retardant Garolite G-10/FR4 Angles

A good all-around choice, these Garolite G-10/FR4 angles are strong, machinable, and electrically insulating. They're made of flame-retardant epoxy resin with fiberglass fabric reinforcement. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.

Arc-Resistant Garolite G-9 Angles

Machine these angles into arc barriers, switch mounts, and components for circuit breakers and electrical equipment. They resist carrying electric currents in dry or humid areas, even when exposed to sudden electric discharge. Strong, they’re also good for making terminal boards and other structural parts. They won’t crack if hit, and they resist breaking while carrying heavy loads. Meets UL 94 V-0 for flame retardance.

Garolite G-9 is also known as electrical-grade Garolite, melamine-grade industrial laminate, phenolic, and Bakelite.

High-Strength Lightweight Carbon Fiber 90° Angles


Round Inside Corner	Square Inside Corner

Lighter than aluminum while remaining rigid, these angles are often used as brackets in structural framing, machinery, and robotics. Known for its use in the aerospace industry, carbon fiber offers a good balance of weight and strength. These angles reduce wear and stress on motorized parts because they are lightweight, extending the life of machinery.

They are made from layers of woven fabric that prevent fibers from splintering when cut. This checked carbon fiber is easy to machine and has a classic carbon fiber-look.
