Overview

The Kupo KG604012 4in Super Viser Clamp End Jaw is a professional-grade grip clamp designed for use on film sets, photo studios, and live event productions. Its aluminum die-cast body strikes a balance between strength and weight, providing enough clamping force to hold lighting fixtures and accessories securely while remaining practical to carry and position on set. The defining feature of this clamp is its grooved alignment shaft, which ensures both jaws track together in the same direction as you tighten, eliminating the uneven pressure and slipping that can occur with conventional clamp designs.

With a jaw capacity of up to 101mm, the Super Viser Clamp accommodates standard pipes, truss sections, and flat planks commonly found in production environments. Rubber pads on the jaw faces protect surfaces from marring and improve grip. The integrated 16mm receiver socket makes the clamp Convi Clamp compatible, enabling quick attachment of additional Kupo grip accessories without the need for separate adapters. Whether you are rigging a light overhead or clamping a flag to a stand, the KG604012 provides a dependable hold with straightforward operation.
