The Strofix upright assembly clamp 42.4mm, Satin is an AISI 304 stainless-steel clamp that grips a Ø42.4 mm railing post without welding. It mounts on a flat surface and secures the post with an M8 screw. Finished in satin. This is a no-weld alternative to the welded base plates.

This assembly clamp anchors an upright Ø42.4 mm post to the floor or structure by clamping rather than welding — the post is inserted and held by the M8 screw, allowing assembly on site without any welding equipment or finishing. This makes it well suited to installations where welding is impractical, where the post may need to be removed or repositioned, or where a clean satin-finished fixing is wanted on show. Unlike the raw welded base plates (which are concealed by covers), this clamp is supplied in a satin finish for a finished appearance.

Use cases:

  • No-weld floor mounting of Ø42.4 mm round railing posts
  • Site assembly where welding equipment is unavailable or impractical
  • Demountable or repositionable post installations
  • Clean satin-finished post fixing left on show
  • Stainless-steel clamp fixing for round railing uprights

FAQ

How does this differ from the welded base plates?

The welded base plates require the post to be welded to the plate. This assembly clamp grips the Ø42.4 mm post mechanically with an M8 screw — no welding is needed, so it can be assembled on site and is demountable.

What post tube does it fit?

The Ø42.4 mm round post tube.

How is the post secured?

The post is clamped and held with an M8 screw.

What finish is it supplied in?

Satin — a finished appearance suitable for being left on show, unlike the raw welded base plates that are concealed by covers.

What steel grade is used?

AISI 304 stainless steel.
