End cap of rod

The Strofix end cap of rod is an AISI 304 stainless-steel finishing cap designed for 10 × 10 or 12 × 12 mm square crossbar rods, providing a clean closure on the cut end of the bar. The 10 × 10 mm cap has a 20 mm height; the 12 × 12 mm cap has a 25 mm height. Supplied in satin finish. The cap is attached using adhesive (elements for pasting included).

The end cap slides over the exposed end of a square crossbar rod and is fixed in place with adhesive, concealing the raw cut edge and creating a smooth, finished appearance. The two size options match the Strofix square crossbar holders (10 × 10 and 12 × 12 mm), ensuring compatibility within the same railing system. AISI 304 stainless steel is suitable for standard interior and exterior installations.

The satin finish provides a uniform appearance that matches other Strofix satin-finished railing components.

• Completing square bar infill railing installations with a polished end closure

About End Caps

An end cap is a stainless-steel closure piece that plugs into or fits over the open end of a railing tube, post or solid bar, sealing it against moisture ingress and giving the termination a clean, finished appearance. Without an end cap, the cut tube end is exposed — visually unfinished and prone to collecting water and debris inside the hollow section.

Strofix supplies 13 end cap products in three profile families: caps for Ø42.4 mm round pipe (available in flat, convex and ellipsoid shapes), caps for 40×40 mm flat square tube (flat profile), and caps for Ø10 and Ø12 mm solid crossbar rods.

All are in AISI 304 stainless steel with a satin finish, with AISI 316 and polished options available on selected variants. The correct end cap depends on the tube or rod profile it will close, and the desired cap shape.
