The Cambo CS-1509 Iris Rod (3.5", 90mm), when used with the CS-151 clamp, offers a memory slot to store the user preset rotation angle of the CS-151 clamp thereby reducing the setup time of the rig. When used with the CS-155 clamp, the rod can be extended in length. It features a 3/8” female thread on both ends. The rod has a high-grade precision aluminum construction, and a PTFE anodized black finish that prevents the rod from wear and tear and improves adjustment settings.
