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.
