Add a set of rods to your rig with this pair of Carbon Fiber 15mm Iris Rods from Cool-Lux. The standard 15mm rods measure 12" in length and are made from lightweight, durable carbon fiber. Each rod features end caps to prevent dirt and debris from getting inside the rods. The rods are slightly undersized at 14.9mm so your 15mm accessories slide smoothly onto and off the rods. The walls of the hollow rods measure 2mm thick to keep them lightweight while maintaining their rigidity.
