Kupo Super Viser Clamp End Jaw 6" 101mm

What the clamp is and who uses it

The Kupo Super Viser Clamp End Jaw is a 6-inch grip tool built from aluminium die-casting and steel. It serves photographers, film crews and stage technicians who need to secure lights, reflectors or accessories to tubes or planks up to 101 mm wide. The integrated 16 mm pin and 16 mm socket accept standard Convi Clamp accessories for flexible rigging.

What to verify on your rig first

Confirm the mounting surface does not exceed 101 mm in thickness, as the movable jaws are limited to that opening. Check that your accessories use a 16 mm pin or socket so they mate with the clamp’s dual receivers. The grooved threaded shaft keeps both jaws aligned in the same direction during tightening, which helps on round or flat stock.

Behaviour during extended use

The aluminium body stays lightweight while the steel components resist deformation under continuous load on set. Jaw alignment remains consistent because the shaft grooves prevent the two faces from rotating apart over long takes. The 16 mm socket and pin maintain a solid connection to accessories without play, even after repeated repositioning during a full shooting day.
