Kupo Nugget Coupler Black 808511

The Kupo Nugget Coupler is a professional-grade connector designed to join lighting and studio equipment securely. It fits tubes with outer diameters from 32mm to 38mm and supports safe working loads up to 120kg (264lbs). Constructed from high-tensile 6061-T6 aluminium with a black anodised finish, it carries TUV approval for verified load capacity. The low-profile design suits permanent installations and portable rigs alike.

Who this suits and who should look elsewhere

This coupler suits technicians and riggers who need a strong, lightweight junction for 32mm to 38mm tubing in lighting grids, truss structures or camera support systems. The M10 and 3/8 inch bolt compatibility allows flexible fastening with standard hardware. Buyers requiring connections for tubes outside the 32mm to 38mm range or load ratings above 120kg should look at alternative clamping solutions.

Bundled hardware and practical impact

The package includes an M10 hex head bolt and nut, enabling immediate assembly without sourcing separate fasteners. A unique safety-wire window lets users attach a secondary retention line for overhead safety compliance. Double-level countersunk recesses accept either M10 or 3/8 inch hex bolts, giving installers a choice of hardware standards on site.
