Endpiece Internal (Internal End Cap) – Topclamp Original

Where the standard endpiece seals a tube from the outside, the endpiece internal (internal end cap) works from within. This fitting is inserted directly into the open end of a tube, creating a flush and clean finish without any visible overlap on the exterior. It is a subtle but important detail for constructions within the Topclamp Original modular building system where a seamless appearance at tube ends is required. Available in tube dimensions of 29.8, 38.4, and 47.1 mm, it is manufactured from high-grade aluminum to match the quality of the broader system.

Like all components in the Topclamp Original range, the internal end cap 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.

The endpiece internal is particularly valued in retail interior design, exhibition construction, and architectural applications where the visual finish of every detail matters. By sitting flush inside the tube rather than capping it from the outside, it delivers a cleaner result that suits high-end builds where exposed fittings would compromise the overall aesthetic. All Topclamp Original components are produced on demand and tailored to exact project requirements.
