1. Engineered for 25,000 Cycles – Long‑Term Reliability
Rigorously tested to withstand 25,000 repetitive open‑close operations – equivalent to decades of daily use. The stainless steel scissor hinges and multi‑point lock mechanism maintain smooth, precise movement without play or wear, ensuring consistent performance over the building’s lifetime.
2. 4‑Step Adjustable Opening Width – Customised Ventilation
The parallel projection distance can be set to 240, 220, 200, or 175 mm via integrated stop‑pegs. This allows you to fine‑tune airflow and emergency escape clearance according to seasonal needs or room usage – a flexibility that fixed‑width systems cannot offer.
3. Heavy‑Load Capacity – Supports Sashes up to 160 kg
Built with reinforced six‑bar friction hinges that handle a maximum 160 kg sash weight (four‑bar configuration supports 120 kg). This high load‑bearing capacity accommodates large‑format double‑glazed or triple‑glazed units, making the system suitable for both residential and high‑rise commercial projects.
4. Wide Sash Compatibility – Fits Most Window Dimensions
The hardware is designed to fit sash widths from 520 to 1200 mm and sash heights from 1250 to 1800 mm. This broad coverage reduces the need for custom‑made components, streamlines inventory, and simplifies specification for architects and contractors.
5. Intuitive Lift‑and‑Push Operation with Integrated LockingSimply lift the handle to push the sash outward in a parallel motion; after closing, press down to engage the multi‑point locking pins. The one‑touch action combines opening, closing, and locking – eliminating complex levers and ensuring a secure seal every time
