Unlike traditional single-chain or friction stay structures, the dual-chain system distributes force more evenly. The window sash moves up and down smoothly without jamming, effectively preventing shaking or detachment risks. This structure significantly increases the load limit of the hardware.
The 100mm wide profile section provides stronger structural support. Combined with premium weatherstripping and multi-seal craftsmanship, it maintains excellent water and air tightness during heavy wind and rain, reducing the risk of leaks.
The window sash can be infinitely adjusted via the crank handle for easy airflow control. The top-hung opening style saves indoor space and eliminates safety hazards associated with outward-opening windows. Remains rain-resistant even when open.
