What Types of Doors and Windows Are Square Spindle Handles Suitable For?  

Square spindle handles feature a square rod connected to a transmission mechanism, allowing users to open, close, or lock doors/windows by rotating the handle. They are ideal for:  

1. Casement Windows/Doors

- Materials: Compatible with aluminum, PVC, thermal break aluminum, etc.  

- Benefits: Enhances sealing and security. Heavy-duty versions are also used for entry/indoor doors to boost safety.  

2. Tilt & Slide Windows

- Mechanism: The spindle directly drives the inclined rod mechanism for seamless operation.  

3. Curtain Wall Opening Sashes  

- Use Case: Heavy-duty square spindle handles are chosen for large hidden-frame curtain walls.  

- Advantages: Supports large sash dimensions while maintaining a minimalist appearance.  

4. Industrial Doors/Windows
