The Adjustable Handrail Support with internal fit is an architectural stainless steel component designed to create a streamlined, concealed connection between handrails and vertical posts or tubes. Engineered specifically for internal mounting into post pipes, this support fitting eliminates visible base plates or outer collars, providing a smooth, flush finish that enhances modern balustrade designs. Equipped with a swivel top ball mechanism, it enables precise multi-angle adjustment and alignment, making it ideal for sloped staircases, ramps, and transition platforms.
The base features a cylindrical push-in sleeve designed with retention tabs to ensure a tight, secure friction fit inside round tubes. It accommodates round tube outer diameters ∅ of 25.4 mm, 38.1 mm, and 50.8 mm with a standard 1.5 mm wall thickness. The upper swivel saddle ∅ 2 = Flat supports flat-bottom handrail bars, maintaining height offsets (A) of 32 mm, 41 mm, or 51 mm from the post top to the pivot center. Precision-cast in AISI 304, AISI 316, and Duplex SS 2205 stainless steel with satin (matte) or mirror (polished) surface treatments, this Handrail Support delivers superior structural load capacity and corrosion resistance for both indoor and outdoor architectural systems.

Q1: How does the internal fit mechanism work during installation?
A: The cylindrical base sleeve inserts directly inside the post tube. Its engineered retention tabs engage with the interior wall of the tube to provide a firm, stable internal friction fit, keeping external joint lines clean and concealed.
Q2: Can this Adjustable Handrail Support be used on sloped staircases?
A: Yes. The swivel top saddle features an adjustable ball mechanism, allowing installers to adjust the pitch angle to match sloped stair handrails or custom ramp inclines.
Q3: What tube sizes and wall thicknesses are compatible?
A: This model is specifically engineered for round post tubing with outer diameters of 25.4 mm, 38.1 mm, and 50.8 mm, designed to fit flush into pipes with a 1.5 mm wall thickness.
Q4: Which material grade should be chosen for outdoor coastal applications?
A: AISI 316 or Duplex SS 2205 stainless steel should be selected for marine or coastal projects. These grades offer high resistance against pitting and saltwater corrosion, ensuring long-term durability in harsh environments.
