Modular Flexible Configuration
Multi-Panel
Up to 6 Panels
Integrated
Flyscreen Ready
The add-on frame system enables effortless multi-sash installations, allowing the system to be extended and adapted to suit varying opening widths and architectural layouts without bespoke fabrication.
A unique dual-function flyscreen sash doubles as a structural mullion, reducing component count while maintaining clean sightlines and maximising the usable glazed area across all configurations.
The KS31.1 CL ES is a modular frame sliding system engineered for dependable, long-term performance. It accommodates a maximum panel size of Window: 1.0 m (w) × 1.8 m (h) and Door: 1.0 m (w) × 2.1 m (h) and accepts glass thickness from 5 to 22 mm across all track configurations.
With a wind load capacity of up to 2 kPa and a robust modular frame construction, the system performs reliably across diverse climatic conditions and project types.
Single and multiple locking mechanisms provide a high level of security, while the integrated flyscreen-as-mullion feature and add-on frame system ensure the KS31.1 CL ES remains the most practical and adaptable sliding solution available.
