Kupo Iron Casting Clamp Black 100kg 38-51mm

Robust iron casting clamp

The Kupo iron casting clamp delivers a secure grip on tubes from 38 to 51 mm in diameter. Its heavy-duty construction supports equipment up to 100 kg or 220 lbs for professional lighting and studio applications. A 2.5 inch steel shaft with a 1/2"-13 yoke bolt ensures a stable connection. The black powder coat finish resists wear and blends into stage environments.

Capacity and headroom

This clamp handles loads up to 100 kg, accommodating most hanging fixtures used in theatre and concert production. It runs out of capacity when equipment exceeds the rated 220 lbs limit or when tube diameters fall outside the 38 to 51 mm range. The square head pan set screw allows fixture rotation for adaptable positioning. It is not suited for buyers who need to mount heavier truss sections or oversized pipes.

Build integration

The clamp fits standard 1.4 to 2.0 inch O.D. iron pipes found on lighting stands and grid systems. Its 2.5 inch shaft length provides clearance for yoke attachment without interfering with adjacent rigging. The yoke bolt and washer are included, freeing the technician from sourcing separate hardware. Builders requiring a different shaft length or pipe diameter must select an alternative clamp.
