Push-fit convex end cap for 42.4mm tube with M8 thread – stainless steel satin

Push-fit convex end cap is an aesthetic finishing element designed to close tubes with diameter 42.4 × 2 mm, used in balustrade and handrail systems. Thanks to the central M8 thread, it enables mounting of additional elements such as handles, decorative spheres or connectors — making it not only a decorative but also functional solution.

The end cap is mounted by pushing the knurled section into the tube opening — the knurls on the perimeter ensure secure and permanent seating without the need for adhesives or additional fixings. This significantly speeds up site installation and eliminates the risk of the element loosening during use.

The end cap is designed for balustrade systems based on Ø 42.4mm tubes — one of the most popular standards in stainless steel balustrades. It works ideally as a top termination for handrails, where the M8 thread allows screwing on a spherical or flat decorative element. Made from AISI 304 steel with satin finish ensures high corrosion resistance and visual consistency with other balustrade components.
