Adjustable flush elbow

The Strofix adjustable flush elbow (90°–180°) is an AISI 304 stainless-steel low-profile variable-angle connector for Ø42.4 × 2 mm railing tubes, with an adjustment range of 90° to 180°. The elbow has a 27 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 anywhere from 90° (right angle) to 180° (straight-line continuation) during installation. The 27 mm height creates a compact, low-profile joint — compared to the taller Ø42.4 mm adjustable flush elbow (SKU LS4247S, H = 47 mm), this version provides a more minimal joint appearance while covering the same full 90°–180° range. The "flush" design encloses the tube ends internally for a smooth external surface. 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 with Ø42.4 mm round tube
• Low-profile variable-angle joints where a compact connector appearance is preferred
• Ramp handrail incline adjustments between 90° and 180°
• Obtuse corner turns on round tube balcony and terrace handrails
• Any Ø42.4 mm round tube joint requiring a variable angle with minimal joint height

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 is the angle adjustment range?

The elbow adjusts from 90° (right angle) to 180° (straight line). This covers staircase pitches, ramp inclines, obtuse corners, and slight directional adjustments.

How does this differ from the other Ø42.4 mm adjustable flush elbow?

The Strofix range includes two adjustable flush elbows for the Ø42.4 mm tube. This low-profile version has a 27 mm height with a specified 90°–180° range. The taller version (SKU LS4247S) has a 47 mm height. Both are adhesive-fixed. Choose the 27 mm version for a more compact joint appearance; choose the 47 mm version when a taller connector body is needed for the specific installation configuration.

What is the elbow height?

The elbow has a 27 mm height (H = 27 mm). This matches the height of the 40 × 40 mm square tube adjustable flush elbow, providing a consistent low-profile joint appearance across both tube systems.

How is the elbow attached?

The elbow is secured using adhesive (pasting). Set the two tubes to the desired angle inside the elbow body, then apply the adhesive. The Strofix anaerobic glue (50 mL) is the recommended adhesive.

What does "flush" mean?

"Flush" means the elbow creates a smooth, uninterrupted surface at the joint. The elbow encloses the tube ends internally, so no bracket, clamp, or protruding hardware is visible on the outside.

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.
