The QLS031.040 slot tube horizontal 90° flush joint elbow is a precision‑engineered corner fitting designed specifically for 40×40mm slotted square tube handrail systems. Manufactured from stainless steel – AISI304 for interior applications and AISI316 for exterior environments – this elbow enables smooth, right‑angle directional changes while maintaining a flush, uninterrupted profile. The engineered geometry engages seamlessly with the tube’s internal slot, delivering a secure, low‑profile joint without protruding elements. Available in mirror or satin finishes, this elbow offers a refined solution for contemporary architectural railing projects.

• Slot‑tube compatibility – engineered to engage with the internal slot of 40×40mm profiled tubes.
• Flush joint design – maintains a smooth, continuous surface profile at the corner transition.
• Horizontal 90° orientation – facilitates precise right‑angle turns in railing layouts.
• Dual material grades – AISI304 for interiors; AISI316 for exterior and coastal installations.
• Two finish options – mirror polished or satin brushed for design flexibility.
• Mechanical engagement – utilises the tube’s existing slot for secure connection; adhesive optional.
• ISO9001 certified – quality assurance with MTC documentation available.
