The Adjustable Wall Flange is a highly versatile and durable stainless steel mounting fitting designed to attach architectural handrail posts securely to wall surfaces, providing critical structural support and flexibility. Engineered for installations requiring precise angle alignment—such as sloped staircases, ramps, and angled walls—this railing base incorporates an articulated stem design to simplify site installation and ensure a flawless fit. Featuring a 6 mm thick mounting base plate with an outer diameter (D) of 80 mm, an overall height (H) of 90 mm, a internal 13 mm central fixing channel, and a tube diameter sized for 42.4 mm round posts, it delivers superior holding strength and clean visual appeal. Manufactured from premium AISI 304, AISI 316, or Duplex SS 2205 stainless steel, these specialized handrail fittings are offered in refined satin brushed or mirror polished surface finishes to suit diverse environmental conditions and modern design preferences.

Q1: What makes an Adjustable Wall Flange ideal for staircase and angled handrail installations?
A: Unlike fixed base plates, an Adjustable Wall Flange allows for pitch and angle adjustments during post positioning. This flexibility makes it ideal for securing handrail posts along stair inclines, transition ramps, or non-standard wall surfaces without requiring custom-bent hardware.
Q2: What are the key technical dimensions of this railing base?
A: Based on the product specification diagram:
Total Height (H): 90 mm
Base Flange Outer Diameter (D): 80 mm
Base Flange Thickness: 6 mm
Tube Outer Diameter: 42.4 mm
Central Fixing Bore: 13 mm inner diameter
Q3: Which stainless steel material grade should I specify for my project?
A: Selection depends on your environmental exposure:
AISI 304 (Satin/Mirror): Designed for interior stairways, residential halls, and climate-controlled commercial buildings.
AISI 316 (Satin/Mirror): Best for outdoor walkways, exterior balconies, and areas exposed to atmospheric humidity and rain.
Duplex SS 2205 (Mirror): Formulated for severe marine environments, beachfront properties, and high-chloride swimming pool enclosures where maximum corrosion resistance is required.
Q4: How is this adjustable wall flange installed onto the wall surface?
A4: The flange is anchored securely to wall studs, masonry, or structural substrates using a heavy-duty central fastener or mounting screw through its 13 mm central channel. Once fixed, the 42.4 mm post tube connects directly over or into the 90 mm stem assembly.
