Kupo Super Convi Clamp with ARRI PSU Rail Mount — 44.5 lbs capacity

SKU CH-KFDT-A1ZDW

A CNC-machined aluminium clamp that grips 0.2″–2.0″ pipes or flat surfaces and adds an ARRI PSU rail mount for cameras, lights or monitors up to 44.5 lbs

  • Secure grip on pipes from 0.2" to 2.0" diameter
  • ARRI PSU rail mount integrates with industry-standard accessories
  • High-grade aluminium construction withstands demanding production environments
  • Supports equipment up to 44.5 lbs safely
  • Spring-loaded jaw and side lever enable quick, firm mounting

Superior Grip Range

The Kupo Super Convi Clamp is a professional rigging tool designed for camera operators and lighting technicians who need to secure gear to pipes or flat surfaces. It accepts diameters from 0.2" to 2.0" (5-51mm) with a spring-loaded jaw that adjusts quickly. A side lever then locks the clamp firmly in place. This clamp suits studio and on-location work where reliable mounting is essential.

Load Limit and Rail Interface

The clamp safely supports equipment up to 44.5 lbs (20 kg), making it suitable for heavier lights, monitors, or power supply units. Its integrated ARRI PSU rail mount allows direct attachment of compatible rail accessories without extra adapters. Users requiring a different mounting standard or a higher weight rating will need an alternative solution.

Aluminum Build and Daily Use

High-grade aluminum construction resists wear from frequent tightening and transport. The CNC-machined plate slides onto ARRI rails smoothly, speeding up setup changes during shoots. The side lever operates with one hand, leaving the other free to position the mounted device. This design favors fast-paced environments where gear is reconfigured often.

Questions about this item

Which pipe diameters can the Super Convi Clamp grip?

The clamp holds round surfaces from 0.2" to 2.0" (5–51 mm) and also locks onto flat surfaces.

What does the 44.5 lbs rating mean when the clamp is on a real rig?

It is the maximum safe load for lights, monitors or cameras mounted on the clamp, provided the pipe or surface can take the same weight.

What does the ARRI PSU rail mount accept in practice?

It slides onto standard ARRI-style rails so you can attach a power supply unit or any accessory with the matching rail foot.
