End cap of rod

The Strofix end cap of rod is an AISI 304 stainless-steel finishing cap designed for Ø12 mm round crossbar rods, providing a clean closure on the cut end of the bar. The cap has a 30 mm height (H) and is supplied in satin finish with screwing elements included.

The end cap fits over the exposed end of a Ø12 mm round crossbar rod and is secured with the included screwing elements, concealing the raw cut edge and creating a smooth, finished appearance. The Ø12 mm diameter matches the Strofix solid round bars and the d = 12 mm bore found on many Strofix crossbar holders — including the vertical crossbar holder, blind-hole bar holders, connecting holders, and standard crossbar holders. 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.

Use cases:

• Finishing cut ends of Ø12 mm round crossbar rods in balustrade systems
• Completing round bar infill railing installations with a polished end closure
• Staircase and balcony railing round bar infill end finishing
• Commercial and residential railing systems with Ø12 mm round crossbar profiles
• Replacement end caps for damaged or missing round rod closures

FAQ:

What rod diameter does this end cap fit?

The end cap fits Ø12 mm round crossbar rods. It is not suitable for square rods — for 10 × 10 or 12 × 12 mm square rod end caps, see the separate square rod end cap product in the Strofix End Caps category.

What is the cap height?

The cap has a 30 mm height (H = 30 mm). This is the distance the cap extends over the rod end.

How is the end cap attached?

The end cap is secured with the included screwing elements. This differs from the square rod end caps in the Strofix range, which use adhesive fixing.

Is this compatible with Strofix crossbar holders?

Yes. The Ø12 mm diameter matches the d = 12 mm bore on many Strofix crossbar holders, including the vertical crossbar holder, blind-hole bar holders (left and right, in Ø42.4 and flat variants), connecting holders, and the standard crossbar holders. Use this end cap on the exposed ends of bars that pass through or terminate in these holders.

What steel grade and finish is used?

The end cap is manufactured from AISI 304 stainless steel with a satin finish. AISI 304 is suitable for standard interior and exterior installations.

Is a Ø10 mm round rod end cap available?

Yes. A separate end cap for Ø10 mm round rods is available in the Strofix End Caps category.

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.
