Overview

The Kupo KG900412 3 Way Clamp is a cast aluminum rigging clamp engineered for professional lighting and grip work. Designed to fit tubes between 1.0 and 1.4 inches in diameter, it secures to standard lighting stands, truss sections, and pipe grids using a spring locking mechanism that latches and releases without tools. This makes setup and repositioning faster during time-sensitive shoots or events where rigging adjustments need to happen quickly.

What sets this clamp apart from simpler C-clamp designs is its three recessed mounting locations, spaced at 90-degree increments around the body. This configuration lets users mount multiple accessories or position a single fixture at the most practical angle without needing additional clamps or adapters. With a 66 lb load rating, the KG900412 handles professional LED panels, fresnel fixtures, and other stage or studio accessories with confidence. The all-metal cast aluminum construction ensures the clamp holds up under repeated use in demanding production environments.
