Crossbar holder - Vertical

The Strofix vertical crossbar holder is an AISI 304 stainless-steel railing component used to mount Ø12 mm crossbars onto Ø42.4 mm railing post tubes in a vertical arrangement. The holder has a 22 mm body diameter, 48 mm overall height, and is supplied in satin finish with screwing elements included.

The vertical crossbar holder features two Ø12 mm holes (d1 and d2) aligned vertically, allowing two horizontal crossbar rods to pass through at a fixed 48 mm centre-to-centre height. The holder slides over or attaches to the Ø42.4 mm post tube and is secured with the included grub screws. AISI 304 stainless steel is suitable for standard interior and exterior railing installations.

The satin finish provides a uniform appearance that matches other Strofix railing components in the same finish, reducing visible fingerprints and micro-scratches.

Use cases:

• Horizontal crossbar infill on residential balcony and terrace railings
• Staircase balustrade crossbar mounting with Ø42.4 mm post systems
• Commercial building exterior railing crossbar infill
• Mezzanine and gallery edge protection with horizontal bar infill
• Pool fencing and garden railing crossbar systems (AISI 304 for inland locations)

FAQ:

What crossbar diameter does this holder accept?

The vertical crossbar holder has two holes of Ø12 mm each (d1 = 12 mm, d2 = 12 mm). It is designed for Ø12 mm solid or hollow crossbar rods.

What post tube diameter does this holder fit?

The holder is designed for Ø42.4 mm railing post tubes. This is the standard post tube size used in Strofix railing systems.

What is the overall height of the holder?

The holder has an overall height of 48 mm (H = 48 mm). This is the total vertical dimension of the component, which sets the vertical spacing between the two crossbar holes.

What is the body diameter?

The holder body has a 22 mm outer diameter (D = 22 mm), providing a compact profile that sits closely against the Ø42.4 mm post tube.

Are screwing elements included?

Yes. The product description states "elements for screwing" are included with the holder, so separate fixings do not need to be purchased for standard installation.

What steel grade and finish is used?

The holder is manufactured from AISI 304 stainless steel with a satin finish. AISI 304 is suitable for standard interior and exterior installations. For coastal or high-humidity environments, check whether an AISI 316 variant is available in the Strofix crossbar holder range.

About Crossbar Holders

A crossbar holder is a stainless-steel fitting that secures a horizontal rod or bar to a railing post, glass panel or flat surface, forming the connection between the infill rod and the structure it passes through.

At intermediate posts the rod runs through the holder; at end posts it terminates in a blind hole (left or right hand); and on glass panels a dedicated glass-mount holder clamps the rod to the panel face.

Strofix supplies 12 crossbar holder products in several configurations: through-hole holders for Ø42.4 mm round pipe and flat-sided posts, left and right blind-hole bar holders for Ø42.4 mm and flat posts, connecting holders for intermediate positions, a vertical holder, and a glass-mount holder — in AISI 304 or AISI 316 stainless steel with satin or polished finishes, with holder heights of 20, 22 and 23 mm for Ø10 and Ø12 mm rod diameters.

The correct holder depends on post profile, rod diameter, position in the railing run and whether the rod terminates or passes through.
