Kupo Mighty Coupler (KCP-851)

Overview

The Kupo Mighty Coupler (KCP-851) is a heavy-duty professional rigging coupler designed for securely mounting lighting fixtures, truss systems, pipes, and structural rigging components in film, broadcast, theatre, stage, and live event environments. Built for high-load applications, this professional-grade coupler delivers exceptional strength, reliability, and safety for demanding production setups.

Constructed from high-tensile 6061-T6 aluminium extrusion, the KCP-851 combines lightweight handling with impressive load-bearing performance. Designed to fit tube diameters ranging from 51 mm to 60 mm, it is ideal for larger truss systems and heavy-duty rigging installations commonly used in professional lighting and staging applications.

The integrated wing nut tightening system allows for fast installation and secure locking onto truss and pipe structures, while the M10 countersunk square bolt ensures smooth operation and improved stability during rigging. A captive thread system helps prevent the wing nut from loosening or falling off during setup, transport, or strike, improving efficiency and on-set safety.

With a safe working load of up to 500 kg and TÜV certification, the KCP-851 is trusted by professional lighting technicians, grip crews, and staging teams worldwide for secure overhead rigging and truss mounting applications.
