NPD A Inward Tilt Turn Hardware System

System Core Capability

Adaptive Pull Rod Geometry

The system offers discrete component options (Item 13 and Item 10) to accommodate variable sash widths from 400mm up to 1000mm, ensuring mechanical leverage is maintained across all scales.

Enhanced Vertical Security

To maintain airtightness and structural stability, the NPD A system requires an increase in the number of locking points when the window height (FH) exceeds 1500mm.

Optimized Load Dynamics

Engineered for standard to heavy residential window sashes, the system safely supports a load capacity below 90Kg, aligning with high-end Aluminum Alloy Hardware requirements.

Aesthetic Versatility

Acknowledging architectural design diversity, the handle style remains optional, allowing for full integration with various interior design themes and user preferences.

Q: How should locking points be distributed?

For optimal sealing and uniform pressure distribution, we suggest keeping the spacing between all locking points within 700mm.

Q: What is the recommended sash ratio?

To ensure long-term mechanical balance and prevent sash drooping, it is highly recommended to maintain a height-to-width window ratio of 1.5 : 1.
