Steel stage clamp with 13mm mounting hole

The Kupo Stage Clamp is a solid steel rigging component built for professional stage and studio environments. It accepts tube diameters from 38mm to 51mm and provides a 13mm hole at the base for attaching lighting fixtures, speakers or other equipment. Rated to hold 110lbs (49.9kg), it delivers a secure grip on standard truss and pipe work.

For riggers needing a single high-capacity clamp

This clamp suits technicians who must mount heavy luminaires or monitors on 38mm to 51mm tubing and require a 13mm attachment point. It is not intended for buyers who need a different mounting thread, a wider jaw range, or a lighter clamp for portable kits. Teams requiring multiple coordinated clamps should verify the hole specification matches their existing hardware.

13mm bottom hole fixes compatibility

The 13mm hole is the critical specification that determines whether the clamp fits your spigot, bolt or mounting plate. If your gear uses a different diameter, the clamp cannot be used without an adapter. The 38mm to 51mm jaw range and 110lb load rating are secondary to this mounting interface.

Questions about this item

Will the 38-51mm jaw grip the 51mm tubes I already use?

Yes, the clamp accommodates tube diameters from 38mm to 51mm, so your existing 51mm tubes fall within the specified range.

How can I confirm the 13mm mounting hole is aligned and secure after installation?

Verify the 13mm hole at the base sits level, then attach your fixture; the 110lbs (49.9kg) rating ensures the steel body holds without slippage.

Does the package include bolts or spigots for the 13mm hole, or must I buy them separately?

The clamp ships as a single steel unit with a 2.0" jaw and 13mm hole; mounting hardware for your fixture is not included.
