Adjustable flush elbow

The Strofix adjustable flush elbow is an AISI 304 stainless-steel handrail connector for Ø42.4 × 2 mm railing tubes, providing a smooth, variable-angle joint between two tube sections. The elbow has a 47 mm height (H) and is supplied in satin finish. Attached using adhesive (elements for pasting included).

The adjustable elbow sleeves over the ends of two Ø42.4 mm tubes and allows the angle between them to be set during installation. This makes it suitable for staircase handrails where the pitch varies between flights, for ramp transitions, and for any configuration where the tube-to-tube angle is not a standard 90°. The "flush" design creates a smooth, uninterrupted surface at the joint — the elbow encloses the tube ends internally, so no visible bracket or clamp appears on the outside. Once the desired angle is set, the elbow is secured in place with the included adhesive. AISI 304 stainless steel is suitable for standard interior and exterior installations.

The satin finish provides a uniform appearance that matches other Strofix satin-finished railing and handrail components.

Use cases:

• Staircase handrail angle transitions between flights and landings
• Ramp handrail transitions at varying inclines
• Balcony handrail direction changes at non-standard angles
• Any Ø42.4 mm tube-to-tube joint where the angle is not 90°
• Creating smooth, flush-profile variable-angle handrail connections

FAQ:

What tube does this elbow fit?

The adjustable flush elbow fits the Ø42.4 × 2 mm round tube — the standard railing pipe in the Strofix product range.

What angle range can this elbow accommodate?

The elbow is adjustable — the angle between the two tubes can be set during installation to match the specific pitch or transition angle. The exact adjustment range is determined by the internal geometry of the elbow body.

What does "flush" mean?

"Flush" means the elbow creates a smooth, uninterrupted joint surface. The elbow sleeves over the tube ends internally, so the outside profile is smooth with no visible bracket, clamp, or protruding hardware.

What is the elbow height?

The elbow has a 47 mm height (H = 47 mm). This is the overall dimension of the elbow body.

How is the elbow attached?

The elbow is secured using adhesive (pasting). Position the two tubes at the desired angle inside the elbow body, then apply the adhesive to fix the joint. The Strofix anaerobic glue (50 mL) from the Chemistry, Adhesives subcategory is the recommended adhesive for this application.

Is a fixed 90° elbow available?

Yes. A separate flush elbow with a fixed 90° angle is available in the Strofix Elbows, Connectors category. Use the fixed 90° version for standard right-angle turns, and this adjustable version for staircase pitches and non-standard angles.

About Elbows & Connectors

Elbows and connectors are stainless-steel joint fittings that link two sections of handrail or railing tube at a change of direction, creating a continuous, seamless-looking rail line around corners, up staircases and across straight joints. Flush elbows and angles slip over the tube ends and produce a smooth, weld-free joint on the visible surface; welding variants are permanently fused for a rigid connection.

Strofix supplies 15 elbow and connector products for Ø42.4 mm round pipe and 40×40 mm flat square tube, including fixed 90° flush angles, adjustable flush elbows (with one variant covering 0–70°), cross flush angles, tee ("T") connectors, tee corner connectors, inline fittings and welding flush angles — all in AISI 304 stainless steel with a satin finish, with AISI 316 and polished options on selected variants.

The correct fitting depends on tube profile, the angle of the direction change, the number of tube arms meeting at the joint and whether a screwable or welded connection is required.
