Quick Reverse Ear for 30mm Square Tube

The Kupo Quick Reverse Ear is a steel connector that clamps onto 30mm square tubes used in lighting and studio rigs. It gives photographers, videographers and DIY riggers a secure mounting point without having to dismantle frame corners. The quick-release mechanism cuts setup and teardown time on location or in the studio. It is built for frequent professional use where stability matters.

Thermals, noise and power draw

This is a passive mechanical accessory with no electronics, fans or power requirements. It produces no heat and makes no audible noise during operation. There is no power draw to consider and no thermal management needed. Performance depends only on the structural integrity of the steel construction.

What the bundled accessories

No accessories, software or mounting hardware are included with the Quick Reverse Ear. The product ships as a single connector unit ready to clamp onto compatible 30mm square tube. Buyers who need additional clamps, safety cables or tube sections must source those separately. There are no firmware updates or driver installations involved.

Questions about this item

How do I install the quick reverse ear onto a 30mm square tube?

Slide the clamp over the tube, align the quick reverse mechanism, and tighten the locking lever until it clicks; the step often missed is fully seating the jaw before locking.

What maintenance will this steel connector need over time?

Periodically wipe dust from the clamping surfaces, check the lever pivot for smooth movement, and apply a drop of light machine oil if the action stiffens.

What is the first limit that appears when the ear is under sustained load?

The clamping force of the quick reverse mechanism is the limiting factor; if the tube shifts, re-tighten the lever to restore grip.
