Purpose and body fitment

The described body window has been specifically designed as a triangular side element, mounted in the front right part of the body. This shape allows for precise filling of the space between the pillar and the door, which contributes to structural rigidity and proper cabin sealing.

Proper fitment to the body lines of the Mercedes W639 series facilitates installation and reduces the risk of stress on the glass. This is particularly important when replacing body components after a collision or during professional body and glass repairs.

Technical characteristics of the AS2 window

The window marked with the AS2 class meets the requirements for side windows regarding light transmission and resistance to mechanical damage. The appropriately selected thickness and structure of the glass ensure:

• dimensional stability in the body frame,
• adequate rigidity while maintaining installation flexibility,
• safe material behavior in the event of damage.

As a result, the window works well with seals and mounting elements, which reduces the risk of wind noise and leaks during operation.

Used condition and benefits of installation

The component comes from the secondary market, which allows for combining rational repair costs with the preservation of the manufacturer's original specifications. A used body window is a good solution in situations where the priority is:

• preserving the factory character of the body,
• reducing costs compared to new parts,
• a visually consistent effect after repairing the side zone.

Before installation, it is worth verifying the condition of the mounting edges, seals, and frame to ensure proper seating of the window and avoid stress during vehicle use.

Professional application in body repairs

The triangular side body window is often replaced during repairs after collisions, parking damage, or during comprehensive body restoration. In body and paint shops, it is used as a complementary element after replacing a door, pillar, or window frame, which allows for restoring the original functionality and aesthetics of the vehicle.

If you are planning a comprehensive repair or upgrade of the side glazing zone in your Mercedes and need other elements from the same group, such as side door windows, additional triangular inserts, or other glazing formats, check the available parts in the Mercedes car windows category.
