The QLS036.6040 slot tube straight connector is a precision‑machined coupling designed specifically for 60×40mm slotted square tubes. Manufactured from stainless steel – AISI304 for interiors and AISI316 for exterior applications – this connector enables seamless inline joining while utilising the tube’s pre‑formed slot for secure mechanical engagement. With a compact height of 6mm, it maintains a low‑profile, near‑invisible connection that preserves the sleek appearance of modern railing systems. Available in mirror or satin finishes, this straight splice offers a reliable, weld‑free solution for extending handrail runs with minimal visual disruption.

• Slot‑tube compatibility – engineered to engage with the internal slot of 60×40mm profiled tubes.
• Low‑profile design – 6mm height ensures discreet, flush‑fitting joints.
• Dual material grades – 304 for dry interiors; 316 for exterior, marine, or high‑humidity environments.
• Mechanical engagement – utilises the tube’s existing slot for secure connection; adhesive optional.
• Two finish options – mirror polished for high‑gloss elegance, satin brushed for a muted, contemporary look.
• ISO9001 certified – quality assured with MTC documentation provided.

Ideal for extending slotted tube handrails in architectural projects, including residential terraces, commercial staircases, hotel balconies, and public walkways. The connector is particularly suited to systems where concealed joints are desired and where the tube’s internal slot facilitates quick alignment and fixing.
