4-way 30° Centre – Topclamp Original

At the intersection of four tubes running at 30° angles, the 4-way 30° centre provides a central junction point that standard perpendicular connectors cannot replicate. It is designed for constructions within the Topclamp Original modular building system where four shallow diagonal connections converge at a single point, enabling frame geometries that blend structural function with distinctive visual form. The fitting is precision-machined from 6063T6 aluminum and available in tube sizes of 29.8, 38.4, and 47.1 mm.

As with all components in the Topclamp Original range, surface treatment options extend well beyond natural aluminum. Anodized, chrome-plated, and nickel-plated finishes are available, as is any RAL color to match the visual identity of the project. The preferred coating is specified in the comments field at the time of ordering.

The 4-way 30° centre is one of the most geometrically demanding fittings in the entire Topclamp Original catalog. It is best suited for projects where four structural elements need to meet at a shallow angle, such as decorative grid ceilings, low-pitched roof structures, or visually complex exhibition installations. Its use signals a level of design ambition that goes well beyond standard modular construction. Everything is produced on demand to exact project specifications
