Function of the Guide Profile

The guide profile is a critical structural component of the S4 cassette system. It:

• Provides the track for the roller blind and flynet
• Ensures smooth, friction‑free sliding
• Maintains correct tension and alignment
• Prevents the blind or flynet from derailing
• Supports the central locking catch mechanism
• Integrates into the cassette frame with precision‑moulded geometry

Without a functioning guide profile, the blind and flynet will bind, jam, or fail to retract correctly.
