Purpose and body fitment

The offered rear left window glass has been designed specifically for the Mercedes-Benz CLC-Class CL203 model, ensuring it maintains the correct curvature, tilt angle, and lower edge line matched to the door guides and seals. Its placement in the rear zone on the left side of the vehicle guarantees compatibility with the factory lifting mechanism and original body components.

Proper window fitment is crucial for:

• lateral door structure rigidity and proper closing,
• reducing cabin noise through proper sealing,
• maintaining the consistent body styling line characteristic of the CLC series.

Technical characteristics of the AS2 glass

The glass belongs to the class designated as AS2, which in practice means tempered glass with controlled light transmission, used as standard in the side windows of many premium class models. This type of glass is designed with user safety in mind – in the event of damage, it shatters into small fragments with limited edge sharpness, which reduces the risk of serious cuts.

AS2 glass parameters also contribute to driving comfort because they:

• ensure an appropriate level of transparency and visibility of the surroundings,
• limit excessive interior heating on sunny days,
• work with factory seals and guides, reducing vibrations and rattling.

Benefits of using original Mercedes glass

Choosing the original rear left window for the Mercedes-Benz CLC-Class CL203 allows you to maintain the technical and visual consistency of the entire body. A component from the same production line as the factory equipment ensures:

• precise fitment with the door frame and seals,
• proper cooperation with the window lifting mechanism,
• maintenance of factory rigidity and acoustic parameters of the side body section.

Thanks to this, the installation process is efficient, without the need for additional modifications or adjustments, and the vehicle retains the original character intended by the manufacturer.

Condition, origin, and use in body and glass repairs

The offered glass is a used component, which represents a reasonable compromise between repair costs and maintaining the original manufacturer quality. Such components are particularly recommended for post-accident repairs, replacing damaged glass after a break-in, or for comprehensive restoration of the side body section.
