Bar holder – Right blind hole - Flat

The Strofix bar holder – right blind hole (flat) is an AISI 304 stainless-steel crossbar end fitting designed for flat mounting surfaces such as rectangular posts, plates, or wall-mounted brackets. The blind hole accepts the crossbar from one side only, making it the correct fitting for the right-hand termination point of a horizontal crossbar run. Available in two height variants (20 or 22 mm) with satin or polished finish, and screwing elements included.

The height variant determines the crossbar bore diameter and body size. The H = 20 mm variant accepts a Ø12 mm crossbar with a 22 mm body diameter, available in both satin and polished finish. The H = 22 mm variant accepts a Ø16 mm crossbar with a 25 mm body diameter, available in satin finish only. All variants use a Ø6.5 mm screw hole for mounting to the flat surface. AISI 304 stainless steel is suitable for standard interior and exterior railing installations.

The satin finish reduces visible fingerprints and micro-scratches; the polished finish (H = 20 mm variant only) provides a mirror-like appearance for installations requiring a high-gloss look.

Use cases:

• Right-hand crossbar termination on flat-surface railing post systems
• End-of-run bar holder on rectangular or square railing posts
• Staircase railing crossbar end fitting on flat-faced newel posts
• Wall-mounted railing systems with horizontal bar infill
• Commercial and residential railings with flat-profile post designs

FAQ:

What crossbar diameter does this holder accept?

The crossbar diameter depends on the height variant selected. H = 20 mm accepts a Ø12 mm crossbar (D = 22 mm body). H = 22 mm accepts a Ø16 mm crossbar (D = 25 mm body). Select the height that matches your crossbar rod diameter.

What does "right blind hole – flat" mean?

A blind hole is a dead-end bore — the crossbar enters from one side but does not pass through. The "right" designation indicates this holder is for the right-hand end of a crossbar run. "Flat" means the holder base is designed for flat mounting surfaces, not curved post tubes. For the opposite end, order the matching left blind hole – flat variant.

How does this differ from the Ø42.4 version?

The flat version has a flat base for mounting on rectangular posts, plates, or wall brackets. The Ø42.4 version has a curved base shaped to sit against a Ø42.4 mm round post tube. Choose the variant that matches your post profile.

Which finish options are available?

The H = 20 mm variant is available in satin or polished finish. The H = 22 mm variant is available in satin finish only. Select the desired finish in the dropdown at order time.

Are screwing elements included?

Yes. Screwing elements are included with the holder. The mounting screw passes through a Ø6.5 mm hole to secure the holder to the flat surface.

What steel grade is used?

The holder is manufactured from AISI 304 stainless steel. AISI 304 is suitable for standard interior and exterior railing installations.

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.
