Kupo

Kupo Nugget Coupler 120 kg silver 32–38 mm

SKU CH-SA3R-1JBMH

A lightweight aluminium coupler joining 32 mm to 38 mm tubes with a 120 kg load rating

  • Stable truss connections minimise wobble during lighting setups
  • High-tensile aluminium construction supports loads up to 120 kg
  • Adjustable diameter range from 32 mm to 38 mm fits various tubes
  • Weighs only .28 kg for easy on-location transport
  • Includes M10 bolt and nut for secure, tool-free assembly

Secure Truss Connection

The Kupo Nugget Coupler is a silver aluminium connector built for professional lighting and studio rigs. It joins tubes from 32 mm to 38 mm in diameter using an included M10 bolt and nut. Rated to 120 kg or 264 lbs, it suits heavy fixtures and overhead displays. The low-profile extrusion keeps the rig compact.

Upgrade From Clamps

This coupler replaces basic clamps or single-bolt joins that can shift under load. The double-level countersunk design locks M10 hardware flush, removing the play that causes wobble on long truss runs. The jump is worth it when a setup sees frequent repositioning or carries near the 120 kg limit. Lighter static loads may not need the extra rigidity.

Diameter And Weight Limits

The coupler only accepts round tube between 32 mm and 38 mm; square or oversize profiles will not fit. Maximum safe load is 120 kg, so larger LED walls or multi-head arrays need additional support points. At 0.28 kg the part adds minimal mass, but the M10 hardware length must match the tube wall thickness used.

Questions about this item

What tube diameters can the Kupo Nugget Coupler 120 kg silver connect?

It fits tubes from 32 mm to 38 mm, covering the 1.26" to 1.5" range for versatile truss mounting.

How is the M10 bolt and nut fitted, and what step is often missed?

The M10 bolt threads into the double-level countersunk holes; the step often missed is fully tightening both the bolt and nut to lock the coupler rigidly.

What maintenance does the silver polished aluminum coupler need over time?

Inspect the M10 bolt and nut for corrosion, re-torque to the original 10 setting, and wipe the finish to preserve the 0.28 kg lightweight profile.
