The Adjustable Wall Mount Flange is a highly specialized architectural hardware component designed to securely attach a handrail tube to a wall or vertical mounting surface while offering critical angular flexibility. This advanced adjustability is essential for a modern railing system running along sloped walls, multi-level staircases, or structural layouts that demand precise angle alignment. Comprising a two-piece articulated system, it features a heavy-duty wall insert plate with a 10 mm profile height and an elongated 16.5 × 8.5 mm mounting slot to house a structural anchor. The main socket collar slides over this foundation piece, allowing installers to adjust the position before locking it down.
Engineered to fulfill demanding architectural requirements, these premium stainless steel handrail fittings are precision-machined to accommodate standard industrial tube outer diameters of 42.4 mm and 48.3 mm. The outer socket housing has a specific collar depth (H), an outer body diameter (D), and dual side set screws to establish a rigid mechanical lock on the inserted handrail pipe without on-site welding. To ensure long-lasting structural strength and corrosion resistance, the assembly is manufactured from high-quality stainless steel grades, including AISI 304, AISI 316, and Duplex SS 2205. Custom surface finishes are available to match diverse design aesthetics, featuring satin polished for interior applications and mirror polished for exterior environments.

Q1. When is it necessary to use an Adjustable Wall Mount Flange instead of a standard fixed flange?
A: An Adjustable Wall Mount Flange is required whenever a handrail run transitions at a slope, such as along ramp inclines or staircases. It allows the mounting core to be fastened flat against a vertical wall while the outer collar adjusts dynamically to accept the tube at its precise installation angle, eliminating custom fabrication on-site.
Q2. How do the two components shown in the diagram fit together?
A: The installation follows a clean, hidden-fastener process:
The low-profile round base plate is bolted flat to the wall using the elongated 16.5 × 8.5 mm internal slot.
The main socket collar (housing the handrail tube) fits over this 10 mm thick base.
The integrated side set screws are tightened to lock the collar onto the base and secure the structural pipe concurrently.
Q3. Which stainless steel grade and surface finish should I choose for my project?
A: Selection is determined by your installation environment to balance aesthetics and durability:
AISI 304 (Satin Polished): Engineered for interior commercial buildings, residential common areas, and indoor stair railings.
AISI 316 (Mirror Polished): Recommended for standard outdoor environments, exterior decks, and areas exposed to rain and ambient moisture.
Duplex SS 2205 (Mirror Polished): Tailored for maximum corrosion resistance in severe coastal, pool fence, or marine applications.
Q4. What tube sizes are compatible with this adjustable flange?
A: This model is engineered to support the most common architectural handrail tube diameters, specifically outer diameters of 42.4 mm and 48.3 mm. Please check your tubing outer diameter dimensions prior to purchasing to guarantee a flush mechanical connection.
