The Strofix bottom fastening is an AISI 304 stainless-steel satin-finished base plate for the Ø42.4 mm railing post tube. The plate has a Ø100 mm diameter (D), 6 mm thickness (h), and four Ø11 mm bolt holes (for M10 bolts). Supplied with a satin finish. The post tube is attached by welding (elements for welding included).
The four-bolt satin base plate provides the maximum anchor security among the satin-finished round tube base plates in the Strofix range. Four M10 fixing points distribute the post loading evenly across the base, providing the highest resistance to overturning moments. The satin finish makes this plate suitable for visible installations where no decorative cover is placed over the base – the polished surface provides a finished appearance matching other Strofix satin-finished railing components. The 6 mm plate thickness provides greater rigidity than the 4 mm raw-surface base plates. AISI 304 stainless steel is suitable for standard interior and exterior installations.
This SKU is a single fixed configuration – Ø100, h = 6, 4 bolt holes, satin, AISI 304 only.
The base plate fits the Ø42.4 mm round post tube – the standard railing pipe in the Strofix product range.
The plate is Ø100 mm diameter (D) with a 6 mm thickness (h). Four Ø11 mm bolt holes accept M10 bolts.
The Strofix range includes three satin-finished base plates for the Ø42.4 mm tube, differing by bolt count: 2-bolt (SKU SP-4210062), 3-bolt (SKU SP-4210063), and this 4-bolt version. All share the satin finish and h = 6 mm thickness. Four bolts provide the highest anchor security; two bolts provide the simplest installation. Choose based on the structural requirements.
Satin-finished base plates are designed for visible installations where the base is not concealed by a decorative cover. The polished surface matches other Strofix satin railing components.
The Ø11 mm bolt holes provide clearance for M10 bolts or anchor rods.
The post tube is welded to the base plate using TIG or MIG welding.
Strofix base plates fix 40x40 mm and Ø42.4 mm railing posts to a floor, stair or deck. Plates run from 80x80 to 105x105 mm and from Ø80 to Ø100 mm, 4–9 mm thick, with 2–4 anchor holes, in AISI 304, AISI 316 and S235.
