Small Piece Internal Tube (Tube Insert) – Topclamp Original

The small piece internal tube is a compact tube insert designed for use within the Topclamp Original modular building system. It slides into the end of a tube and acts as a short internal extension, enabling an offset connection where a smaller tube is inserted directly into a connector rather than running straight through it. Without this tube insert, an offset connection within the Topclamp Original system would not be possible. It is available in tube dimensions of 29.8, 38.4, and 47.1 mm.

Like all other Topclamp Original components, the small piece internal tube can be supplied in natural aluminum or finished to specification. Anodized, chrome-plated, and nickel-plated treatments are available alongside any RAL color. The preferred finish is noted in the order comments field when placing an order.

Despite its compact size, the small piece internal tube plays a critical role in the overall flexibility of the Topclamp Original system. It is the component that makes offset connections possible across the entire range of connectors, from simple two-way fittings to complex multi-directional junctions. Whether the application is a trade show booth, a retail display, or an architectural installation, having the right tube insert on hand ensures that the assembly process runs smoothly and the finished construction meets the intended design. All Topclamp Original products are manufactured on demand.
