Adjustable Support Flat

Adjustable flat square supports are designed to mount handrails or tubular rail runs where a flat or square fixing surface is required, while still allowing angle adjustment during installation. This flexibility makes them especially useful in handrail systems installed on stairs, ramps, and sloped walkways, where rail angles must be accurately aligned for both safety and visual consistency.

The flat square base provides a stable mounting face that can be securely fixed to walls, posts, stringers, or structural members. The adjustable joint allows the support to be set to the correct angle, ensuring the handrail sits comfortably in the hand and follows the slope of the stair or ramp. This adjustability helps reduce on-site fabrication and simplifies installation, particularly when working with varying angles or site conditions.

Manufactured from Grade 316 stainless steel, these supports offer excellent corrosion resistance and long-term durability. Grade 316 contains molybdenum, which significantly improves resistance to chlorides, moisture, and harsh environmental exposure. As a result, these handrail supports are well suited to external installations, coastal and marine environments, poolside areas, and other locations where corrosion resistance is critical.

Finish options include satin and mirror polish, allowing the supports to be matched to the handrail tube and surrounding fittings for a cohesive architectural appearance. Satin finishes provide a subtle, low-glare look that helps hide fingerprints and light marks, while mirror finishes deliver a high-end, reflective appearance ideal for premium architectural settings. Both finishes offer smooth surfaces that are easy to clean and maintain.

Adjustable flat square supports are commonly used in residential, commercial, and public handrail installations, including staircases, access ramps, balconies, and walkways. They are compatible with standard stainless steel handrail tube sizes and are designed for secure attachment when installed correctly.

To ensure a proper fit and safe performance, select the correct support size to match the handrail or tube diameter. For projects requiring adjustability, durability, and a professional finish, Grade 316 stainless steel adjustable flat square supports are a reliable and widely specified solution.
