The Stainless Steel Round End Cap is a precision architectural fitting designed to cap tubular balustrades, posts, and handrails with a clean, flush aesthetic. Engineered for a secure press-fit installation, this cap features a central M8 tapped hole that allows for seamless integration with top handrail support brackets, saddles, or secondary hardware.
This round cap matches standard tube outer diameters (Ø) of 1.5 inches (38.1 mm) and 2 inches (50.8 mm). It features a 10 mm insertion skirt depth (A) equipped with a ribbed/knurled push-fit sleeve that seats firmly inside the tube wall, alongside a central M8 threaded hole (B) for hardware attachment. Precision-cast in high-performance AISI 304, AISI 316, or Duplex SS 2205 stainless steel and available in brushed satin or mirror-polished finishes, these versatile handrail fittings provide long-lasting durability and corrosion resistance as a reliable Handrail Support accessory in residential, commercial, and marine balustrade applications.
