4.1 Measuring Track Length
Accurate measurement is crucial for optimal performance. Determine the required track length based on your window or wall dimensions.
- Curtain covers the whole wall: Track Length = Wall Width - 4cm
- Curtain covers the window only: Track Length = Window Width + 60cm
- Curtain with U/L Shape Track: Track Length = Sum of all segments (e.g., AB + BC + CD)

4.2 Track Assembly and Configuration
The track system is modular and can be assembled to your desired length using the provided segments and spliced track connectors. Ensure all seams are securely connected for smooth operation.
