The Falcon Eyes CL-35AL Shelf Clamp is a universal metal clamp equipped with a spigot. The CL-35AL can be clamped onto a table or thin board of between 10-35mm thick, making it suitable for use in the studio or on location. The screw mechanism makes the CL-35AL easy and quick to adjust and the rubber coating prevents damage and slipping. A speedlite or flexible arm can be mounted upon the fixed ¼” spigot.
