End cap

The Strofix handrail end cap is an AISI 304 stainless-steel satin-finished closure for the 40 × 40 × 1.5 mm handrail tube. The cap has a 4 mm height (H) and provides a flat, flush closure on the cut end of the handrail. Attached using adhesive (elements for pasting included).

The end cap slides over or into the open end of the 40 × 40 × 1.5 mm handrail tube and is secured with adhesive, concealing the raw cut edge with a smooth, finished surface. The 40 × 40 × 1.5 mm specification refers to the thinner-walled handrail tube used in the Strofix glass railing handrail system — this is distinct from the standard 40 × 40 × 2 mm railing tube used for posts and structural framing. The satin finish matches other Strofix satin-finished handrail and railing components, providing a consistent appearance at the visible handrail termination. AISI 304 stainless steel is suitable for standard interior and exterior installations.

This SKU is a single fixed configuration — 40 × 40 × 1.5, h = 4, satin, AISI 304 only.

Use cases:

• Closing the open end of 40 × 40 × 1.5 mm handrail tubes at wall terminations
• Finishing handrail ends at staircase terminations and balcony corners
• Providing a smooth, safe end surface on exposed handrail tube ends
• Completing applied handrail installations with a clean end closure
• Sealing handrail tube ends against moisture and debris

FAQ:

What tube does this end cap fit?

The end cap fits the 40 × 40 × 1.5 mm handrail tube from the Strofix Handrails category. This is the thinner-walled handrail tube — not the standard 40 × 40 × 2 mm railing tube used for posts and framing. Check the wall thickness of the tube before ordering.

What is the cap height?

The cap has a 4 mm height (H = 4 mm), creating a flat, near-flush profile on the tube end.

How does this differ from the 40 × 40 mm end caps in the End Caps category?

The end caps in the End Caps category fit the 40 × 40 × 2 mm railing tube. This handrail end cap fits the 40 × 40 × 1.5 mm handrail tube, which has a thinner wall. The different wall thicknesses mean the internal bore dimensions differ, so the end caps are not interchangeable between the two tube types.

How is the end cap attached?

The end cap is attached using adhesive (pasting). The Strofix anaerobic glue (50 mL) from the Chemistry, Adhesives subcategory is the recommended adhesive.

What steel grade and finish is used?

AISI 304 stainless steel with a satin finish. The satin finish matches other Strofix handrail components.

Is this compatible with Strofix handrail fittings?

Yes. The end cap is part of the Strofix Handrails system, alongside the axial handrail fastenings, handrail fittings, horizontal and vertical fittings, and the applied handrail — all designed for the 40 × 40 × 1.5 mm handrail tube.

About Handrails

A handrail is the graspable top rail of a balustrade system, running along the upper edge of railing posts or the top of a glass panel to provide a secure handhold. The handrail profile sits on handrail supports or is fixed directly to the glass via a channel bar, and fittings at each joint — elbows, end caps and axial connectors — allow the rail to follow corners, stair pitches and direction changes.

Strofix supplies handrails and handrail components in two profile systems: a 40×40 mm flat square profile and a Ø42.4 × 15 mm oval (D-shaped) profile for glass-top mounting, both in AISI 304 stainless steel with a satin finish. The range includes applied handrail lengths (2500 mm), channel bars in AISI 304 and aluminium for glass-top fixing, clamping rubbers for glass thicknesses from 8 to 21.52 mm, end caps, axial fastenings, handrail fittings, horizontal and vertical 90° fittings, and flush adjustable elbows.

The correct components depend on handrail profile, mounting method (post-top or glass-top) and the railing layout.
