The 50.8mm Round Weld-On Post Converter is a flat mounting plate that is welded permanently to the top of a 50.8mm round stainless steel post, converting it to accept a wooden or custom handrail. Unlike the knock-in version, it has no inner stem — it sits on top of the post and is welded around the base of the plate by the installer, creating a solid, permanently fixed mounting point that becomes structurally part of the post.

The weld-on converter is the correct choice for fully welded post assemblies where a permanent, mechanically integrated fitting is required. Once welded and finished, the converter plate is completely secure and provides a stable, flat surface for fixing a timber, composite, or custom handrail profile directly.

Post-weld finishing is the responsibility of the installer. Available in Grade 304 brushed satin for inland and non-coastal environments, or Grade 316 mirror polish for coastal and outdoor applications.

Which Grade Should I Choose?

Grade 304 is strong and reliable, suited to internal applications and external use in non-coastal, non-corrosive environments — ideal for inland areas such as Johannesburg, Pretoria, and most non-coastal suburbs.

Grade 316 (Marine Grade) offers superior corrosion resistance and is the essential choice for coastal properties, poolside installations, and any environment exposed to salt air, moisture, or chemicals. If you are in Cape Town, the Winelands, Durban, or any coastal area, Grade 316 is strongly recommended.
