The Strofix base for welding 42.4×80×4mm, RAW, 2 screws is an AISI 304 stainless-steel round base plate for the Ø42.4 mm railing post tube. The plate is Ø80 mm in diameter (D), 4 mm thick (h), with two Ø8.5 mm bolt holes for M8 bolts. Supplied with a raw (unfinished) surface. The post tube is attached by welding.

The Ø80 mm round plate provides a compact circular footprint that matches the round Ø42.4 mm post tube. The two-bolt anchor pattern suits simpler installations with lower loads; a three-bolt option is also available for increased stability. The Ø8.5 mm bolt holes accept M8 bolts or anchor rods. This is the most compact and economical base plate for the Ø42.4 mm round tube in the Strofix range. The raw surface is standard for base plates that are concealed by a decorative cover after installation. AISI 304 stainless steel suits standard interior and exterior installations.

Use cases:

  • Compact floor mounting of Ø42.4 mm round railing post tubes
  • Two-bolt anchor pattern for light-duty residential railing installations
  • Budget base plate for Ø42.4 mm round tube railing systems
  • Installations where a Ø80 mm circular base footprint is preferred
