Kupo Arch Coupler 16mm Stud

The Kupo Arch Coupler is a precision-engineered mounting accessory built from high-tensile aluminium and steel alloy. It features a 16mm stud for attaching lighting fixtures and a low-profile clamp designed for professional photography and videography rigs. The silver finish resists wear during frequent handling on set or in the studio.

Suits 38-51mm tube diameters

This coupler suits gaffers and riggers securing heavy lights to truss pipes or scaffold tubes between 38mm and 51mm (1.5 to 2.0 inches). It is not for buyers needing to clamp flat surfaces, square profiles or pipes outside the stated round-tube range. Studios requiring tool-free rapid release should verify the locking mechanism matches their workflow.

100kg load capacity headroom

Rated at 100kg (220lbs), the coupler comfortably handles large Fresnels, LED panels and modifier bundles on a single point. Headroom shrinks when the load extends far from the clamp centre or when dynamic movement adds leverage. It runs out for overhead arrays exceeding the rated limit or where secondary safety cables are mandatory by regulation.

Questions about this item

What diameter tube or truss must I already have for the 38-51mm clamp range to fit?

The arch coupler accepts round tubes from 38mm up to 51mm (1.5 in to 2.0 in), so you need a truss or pipe within that range.

Will the 16mm stud on this coupler match the 16mm receiver on my existing light or grip head?

Yes, the built-in 16mm stud is the industry-standard baby-pin size, so it slides directly into any 16mm female receiver on lights, arms or grip heads you already own.

How can I confirm the coupler is holding its full 100kg rating after I tighten it on the truss?

With the clamp jaws fully closed on a 38-51mm tube and the locking handle seated flush, the silver aluminium-and-steel body shows no visible flex when a 100kg load is applied.
