Crossbar holder

The Strofix crossbar holder is an AISI 304 stainless-steel railing component used to mount square crossbar tubes in balustrade and railing systems. Available in two square tube sizes — 10 × 10 mm or 12 × 12 mm — with satin finish and screwing elements included.

The holder body dimensions vary by tube size: the 10 × 10 mm variant has a 30 mm height (H) and 20 × 20 mm body (a × b), while the 12 × 12 mm variant has a 31 mm height and 22 × 22 mm body. The holder is secured to the railing post or mounting surface with the included screwing elements. Select the correct tube size at order time to match the square crossbar profile specified for the project. 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:

• Square crossbar infill on residential balcony and terrace railings
• Staircase balustrade systems with 10 × 10 or 12 × 12 mm square bar infill
• Commercial building railing systems with square bar design
• Mezzanine and gallery edge protection with horizontal square bar infill
• Garden and perimeter railings with square crossbar detailing

FAQ:

What square tube sizes does this holder accept?

The holder is available in two variants: 10 × 10 mm and 12 × 12 mm square tubes. Select the correct size at order time to match the square crossbar profile used in the railing system.

What are the holder body dimensions?

For the 10 × 10 mm variant: H = 30 mm, a = 20 mm, b = 20 mm. For the 12 × 12 mm variant: H = 31 mm, a = 22 mm, b = 22 mm. The body dimensions scale with the tube size.

Are screwing elements included?

Yes. Screwing elements are included with the holder, so separate fixings do not need to be purchased for standard installation.

Can this holder be used with round crossbar tubes?

No. This holder is designed specifically for square crossbar tubes (10 × 10 or 12 × 12 mm). For round crossbar pipes, see other Strofix crossbar holders designed for round profiles such as the Ø12 mm or Ø16 mm variants.

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.

Are the 10 × 10 and 12 × 12 mm variants interchangeable?

No. Each variant is sized to accept only its designated square tube dimension. A 10 × 10 mm holder will not accept a 12 × 12 mm tube, and vice versa. Verify the crossbar profile size before ordering.

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.
