25.4mm, 38.1mm, 50.8mm
The Oblong Base Flange is a stainless steel mounting component designed to provide a secure and stable attachment point for handrail posts. Engineered for use in both residential and commercial railing systems, this flange ensures reliable structural support when fixing handrails to floors, walls, or other solid surfaces.
Featuring an oblong (oval) footprint with pre-drilled mounting holes, the flange distributes load evenly and enhances installation stability. Manufactured from high-quality AISI 304 or AISI 316 stainless steel, it offers excellent corrosion resistance, making it suitable for indoor and outdoor environments. Available in Satin or Mirror polished finishes, the oblong base flange combines structural performance with a clean architectural appearance.
Compatible with common railing tube diameters such as 25.4 mm, 38.1 mm, and 50.8 mm, this component is an essential element in professional handrail fittings systems.

Q1: What is the primary purpose of an Oblong Base Flange?
A: The primary function is to provide a secure and decorative method for attaching a handrail to a surface like a wall or floor. It creates a stable and rigid base that is essential for the safety of staircases and balconies.
Q2: Which material grade is recommended for outdoor use?
A: For most exterior handrail fittings, 316-grade stainless steel is the industry standard due to its superior resistance to corrosion and "tea-staining" in outdoor or coastal environments. Grade 304 is best suited for indoor or low-moisture areas.
Q3: What sizes are available for this flange?
A: These flanges are commonly designed to fit standard railing tubing diameters of 25.4mm, 38.1mm, and 50.8mm. Always ensure your tubing diameter matches the internal diameter of the flange for a secure fit.
Q4: Can this be used to mount a railing to a wall?
A: Yes. The Oblong Base Flange is versatile and can be used for securely mounting railings to vertical walls as well as horizontal floors or landings.
Q5: How is the flange installed?
A: The flange features a pre-drilled footprint for screwing or anchoring into place. For post-to-flange connectivity, high-strength adhesive or mechanical fastening is typically used to ensure a non-slip, permanent bond.
