Designed for use as an accessory or substitute for a light stand or on its own as a support, the Center Jaw, 3" Super Viser Clamp from Kupo is a highly useful accessory on set or in the field. The clamp has a 3" main bolt with a channel (chamfered slot) cut into it to prevent its jaws from rotating when in use. Each clamp jaw is covered in a removable rubber surface that guaranties objects hold fast and aren't scratched. Capable of handling items weighing up to 66.1 lb, the clamp terminates in an industry-standard knurled 5/8" pin.
