NPD B Premium
Tilt Turn System

Advanced Aluminum Alloy Hardware for mid-scale window sashes. A centerpiece of Premium Hardware Solutions designed for precision operation and structural endurance.

90KG Max Load Limit

450-750mm Optimized FB Range

Mechanical Sophistication
For Modern Building Skins

The NPD-B Premium Inward Tilt Turn System is a high-caliber Window Hardware solution tailored for aluminum profiles. Engineered by Luoqi Door Systems, this B-series variant is specifically optimized for sashes within the 450mm to 750mm width threshold, providing an impeccable balance between ventilation performance and hardware leverage.

This system allows for the sophisticated "tilt before turn" operation, which facilitates draft-free ventilation while maintaining high levels of security. By focusing on aluminum alloy Hardware excellence, the NPD-B ensures that every interaction—from tilting the sash for airflow to turning it for maintenance—remains smooth, quiet, and structurally sound under its rated load capacity.

Operational Logic

• Precision Inward Tilt Movement
• High-Friction Security Locking
• 180° Turn Full Access Opening
• Durable Surface Coating (SST)
• Anti-Slam Safety Mechanisms

Structural Design Integrity

Deploying NPD-B Premium Hardware Solutions for long-cycle reliability.

Mid-Range FB Optimization

The NPD-B series is finely tuned for window widths between 450mm and 750mm. This specialization ensures that pull rods and corner drives operate at peak mechanical efficiency without excessive torque on the handle.

High-Height Adaptive Locking

For architectural requirements where window height (FH) exceeds 1500mm, the system is designed to support additional locking points, preventing profile bowing and ensuring consistent air-sealing.

Robust Static Load Rating

With a tested capacity below 90Kg, this Window Hardware system accommodates standard to heavy double-glazed units, providing significant safety margins for residential and commercial use.

Proportional Equilibrium

Maintaining a 1.5:1 height-to-width ratio ensures the system's center of gravity remains optimized, reducing wear on the lower hinges and maintaining sash alignment for years.

Engineering Best Practices

To guarantee the maximum performance of Luoqi Door Systems hardware, the following configuration guidelines are recommended by our technical team.

◈ Optimal Point Spacing

We strongly suggest maintaining a distribution spacing of lock points within 700mm. This density ensures uniform pressure across the EPDM gaskets, enhancing thermal and acoustic insulation.

◈ Handling Sash Geometry

For high-performance Aluminum Alloy Hardware longevity, keep the window ratio (height/width) at 1.5:1. Deviating significantly from this ratio may increase mechanical stress during the turn operation.
