This clamp combines user-friendliness with strength and light weight. Product Name: PCL-60 Quick Release Clamp Reason for Listing: I like this clamp very much and find it easy to use, so I bought many and attached them to all my ball heads. I am selling some of the ball heads I wasn't using, so I am listing the panning clamps that were attached to them. Condition: Since it was attached to ball heads that were hardly used, there are only scratches on the bottom where it attaches to the ball head. It functions without any problems. *The included plate is not included. Diameter: 60mm Width (Max): 90mm Thickness: 26mm Mounting Screw: 1/4 inch (fine thread) / 3/8 inch (coarse thread) Weight: 168g
