The Strofix external corner side mounting of the post 42.4mm, Satin is an AISI 304 stainless-steel corner side fastening that anchors a Ø42.4 mm railing post at the external corner of a structure. Its angled plate wraps the outside corner of a slab, beam, or wall, holding the post where two faces meet. Finished in satin. The post is attached by welding.

This is the corner version of the side fastening, shaped to fit an external (outside) corner where two vertical faces meet at an angle — for example, the outside corner of a balcony slab. A standard flat side fastening cannot bridge a corner cleanly; this angled fitting bears against both faces, transferring the post load around the corner. It is the most substantial side fastening in the range, reflecting the more complex geometry and the loads it carries at a corner. It is used where a railing must turn an external corner while side-mounted, keeping the floor surface clear.

Use cases:

  • Side-mounting a Ø42.4 mm railing post at the external corner of a slab or balcony
  • Turning a side-mounted railing around an outside corner
  • Corner fixings where two vertical faces meet at an angle
  • Keeping the floor/deck surface clear at corner posts
  • Stainless-steel external corner side fastening for round railing posts

FAQ

What is an external corner side fastening for?

It anchors a railing post at the external (outside) corner of a structure, where two vertical faces meet. Its angled plate bears against both faces, which a standard flat side fastening cannot do.

What post does it fit?

The Ø42.4 mm round post tube, attached by welding.

How does it differ from the standard side fastenings?

The standard side fastenings have a flat plate for a single vertical face. This version is shaped for an external corner, bridging two faces at the corner.

Why is it the most expensive side fastening?

The corner geometry is more complex and carries the post load around an external corner, requiring more material and fabrication.

What steel grade and finish are used?

AISI 304 stainless steel with a satin finish.
