Crossbar holder for 12mm, 42.4, Satin

The Strofix crossbar holder for 12mm, 42.4, Satin is an AISI 304 stainless-steel fitting that secures a horizontal Ø12 mm crossbar (infill rod) to a round Ø42.4 mm post tube. Its base is curved to seat against the round post, and it holds the rod through a bore, at intermediate positions where the rod passes straight through. Available in AISI 304 or AISI 316, satin finish.

This is the tube-mount version of the crossbar holder, shaped to fit the Ø42.4 mm round railing post – where the flat version seats against a flat post face, this one has a saddle profile matching the curve of the round tube. It forms the connection between a horizontal infill rod and the round post at intermediate positions in a railing run, with the rod passing straight through the holder to the next support. The AISI 316 grade option suits coastal or high-humidity installations.

Use cases:

• Securing a horizontal Ø12 mm infill rod to a round Ø42.4 mm post
• Through-hole crossbar support on round-tube posts at intermediate positions
• Rod-infill balustrades built on Ø42.4 mm round posts

About Crossbar Holders

A crossbar holder is a stainless-steel fitting that carries a horizontal Ø12 mm rod on a railing post or a flat surface. At intermediate posts the rod runs through the holder; at end posts it ends in a left or right holder with a blind hole.

Strofix supplies 16 crossbar holders: eight for flat surfaces and eight for Ø42.4 mm round posts – through, left and right end, connecting, front and adjustable front holders, plus a vertical holder and a holder for 1.5–4 mm glass – in AISI 304 (one through holder also in AISI 316), satin or polished, all for Ø12 mm rods.

The correct holder depends on the post profile, the position in the railing run and whether the crossbar follows a stair.
