  • Safely supports 66.1 lbs (29.98 kg) for heavy lighting rigs

Heavy-duty grip for production rigs

The Kupo 3" Super Viser Clamp with Center Jaw secures lighting fixtures, cameras and accessories to pipes, stands or truss from .5 inch to 3 inches thick. Its steel and aluminium body supports up to 66.1 lbs (29.98 kg) without slipping. A 5/8 inch baby stud on one end adds a standard mounting point for heads and arms. The grooved channel keeps jaws aligned and prevents unwanted rotation under load.

Replaces lighter clamps that slip under weight

Standard spring clamps or small C-clamps often lose grip on thicker tubes or when a heavy modifier is added. This clamp’s wider jaw range and 66.1 lb rating make the jump worthwhile whenever the load exceeds what a light-duty grip can hold safely. It is not for rigs that need a wider opening than 3 inches or a lower profile for tight clearance.

Holds alignment through long shoot days

The centre jaw and grooved channel distribute clamping force evenly, so the connection stays rigid over hours of continuous use. Steel construction resists fatigue where lighter alloys can deform. The chrome finish protects against corrosion in humid studios or outdoor locations. No periodic re-tightening is required once the clamp is set.

Questions about this item

What surface thickness does the center jaw accept?

The center jaw grips surfaces from 0.5 in to 3 in thick, covering pipes, rails and boards in that range.

How do you secure the 5/8 in baby stud so it does not rotate under load?

Tighten the grooved-channel locking screw after positioning the stud; the channel teeth lock the jaw angle and stop rotation.

Which parts wear first and need periodic inspection?

The chrome-finished steel jaws, the aluminum handle threads and the grooved channel teeth should be checked for deformation or stripped threads after heavy use.
