Flange Joint Two-Sided Internal – Topclamp Original

Building on the same internal mounting concept, the flange joint two-sided internal inserts into a tube and secures it between two parallel surfaces simultaneously. Where the one-sided internal variant anchors to a single surface, this flange joint two-sided internal clamps the tube at two fixed points from within, providing additional stability for constructions that run alongside walls, partitions, or structural panels. It is part of the Topclamp Original modular building system and available in tube dimensions of 29.8, 38.4, and 47.1 mm.

As with every component in the Topclamp Original range, surface finishing options are extensive. Natural aluminum is standard, but the fitting can be delivered in any RAL color or treated with an anodized, chrome-plated, or nickel-plated coating. Finishing preferences are communicated through the order comments field prior to production.

The flange joint two sided internal is the internal counterpart of the external two-sided variant, chosen specifically for projects where the mounting hardware needs to remain hidden within the tube profile. Retail interiors, architectural installations, and premium exhibition builds where a seamless exterior finish is non-negotiable are the primary applications for this fitting. All Topclamp Original products are manufactured to order and tailored to exact project dimensions.​
