Designed for use as an accessory or substitute for a light stand or on its own as a support, the End Jaw, 4″ Super Viser Clamp from Kupo is a highly useful accessory on set or in the field. The clamp has a 4″ 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 has a knurled 5/8″ pin at one end and a hex receiver at the other for additional mounting options.
