The Stainless Steel Base Flange is a robust base flange designed to securely fix 50.8×50.8mm square tube posts to flat surfaces such as floors, decks, or concrete bases in railing systems. As an essential component of Square Tube Handrail Fittings, it provides a stable foundation for handrails used in staircases, balconies, and guardrails. The square plate features pre-drilled holes for bolts or anchors, ensuring a firm and reliable installation across different substrates. Manufactured from high-quality stainless steel 304 or 316, it offers excellent corrosion resistance and durability for both indoor and outdoor applications. With precise dimensions of □A = 100mm outer plate and □B = 50.8mm inner opening, along with satin or mirror polished finishes, this base flange ensures accurate fitment while enhancing the clean, modern appearance of railing systems.
