Upright assembly clamp 42.4mm, Satin

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
