The Adjustable Tube Joiner is a specialized, high-strength swivel connector designed to join 50.8mm x 50.8mm square stainless steel tubing at variable angles. Featuring a flexible range of motion from 0° to 70°, this tube connector is the ideal solution for custom architectural installations where fixed-angle fittings are insufficient. With precision-engineered offsets of 37.5mm for both the fixed and adjustable sections, it provides a seamless and structurally sound transition for complex railing geometries.
Constructed from premium AISI 304 or 316 grade stainless steel, this square handrail fitting offers exceptional durability and a modern aesthetic. The internal flush-fit design eliminates the need for on-site welding, allowing for a clean, professional finish on staircases, ramps, and balconies. Whether used in a frameless glass system or a traditional post-supported design, the Adjustable Tube Joiner ensures that handrails can follow slopes and turns with precision and ease.

Q1. What is the adjustable range of this connector?
A: The Adjustable Tube Joiner features a swivel joint that allows for a precise range of motion between 0° and 70°, making it highly adaptable for various staircase pitches and custom turns.
Q2. What tube size is compatible with this fitting?
A: This connector is specifically engineered to fit standard 50.8mm x 50.8mm square stainless steel tubing. The joint legs slide internally into the tube ends to provide a flush, high-strength connection.
Q3. Which material grade should I choose for an outdoor ramp?
A: For all outdoor, coastal, or high-moisture environments, SS316 is mandatory to ensure maximum corrosion resistance and a long service life. SS304 is suitable for interior applications in dry, controlled environments.
Q4. How is the Adjustable Tube Joiner installed without welding?
A: These handrail tube fittings are designed for a weld-free installation. They are typically secured using high-strength structural adhesives or internal mechanical fasteners, which maintain a clean appearance and simplify the assembly process.
Q5. Does this fitting support structural safety requirements?
A: Yes. When properly bonded to the tubing and anchored within the railing framework, the Adjustable Tube Joiner helps the system meet rigorous structural performance standards for point loads and safety compliance.
