Carbon Fiber Slip-On Framing and Fittings
Stronger than plastic and aluminum, this is the lightest weight framing we offer. It has good resistance to chemicals and salt water. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Drill rails and connect fittings with the included hardware.

Ultra-Strength Lightweight Carbon Fiber U-Channels

- Color: Black
- Tensile Strength: 103,000 psi (Excellent)
- Fiber Tensile Stiffness: Standard (33-36 msi)
- Maximum Temperature: 275° F
- Impact Strength: Not Rated
- Hardness: Not Rated

Often used to make railings, edge covers, and other structural framing parts, these carbon fiber U-channels add stiffness and strength to applications without adding a lot of weight. They’re similar in strength to 6061 aluminum yet lighter in weight. With a plain weave and 0°/90° construction layup, all are easy to machine. They won’t splinter when cut.
