Purpose and Fitment

The presented window is designed for installation in the rear right side of the body. Its construction corresponds to the factory standards of the Mercedes brand, which translates to a correct fit with seals, door frames or side panels, and interior trim elements. Such a fit minimizes the risk of glass stress and leaks after installation.

As a component from the Automotive Glass group, the rear side window works with factory mounting points and the body system, allowing for the preservation of the vehicle's original structural rigidity and proper aerodynamics of the side body section.

Technical and Visual Characteristics

The window is marked with AS3 class, which in practice means the use of tinted glass with parameters intended for rear and side glazing. This type of solution helps reduce interior heating and improves optical comfort for rear seat passengers.

The black edge finish complements the factory trim strips and seals, resulting in a cohesive, aesthetic appearance of the side body after installation. This color choice also facilitates the integration of the window with styling packages that feature dark frames and contrasting details.

Condition of the Part and Practical Application

The offered window is a used part, making it a sensible choice for post-accident repairs, bodywork and paint corrections, or replacement of damaged glazing without the need to invest in a new component. In many cases, this allows for the restoration of full functionality and aesthetics of the side body while maintaining a favorable repair budget.

Due to its factory origin, the window retains the correct profile, thickness, and geometry, which facilitates the work of the installation workshop and minimizes fitting time. This is particularly important for precise glass seating in the rear body area, where sealing and the absence of stress are crucial.

Benefits of Installing an Original Side Window

• Maintenance of the original side body line and visual consistency with other glazing.
• Predictable glass performance in use due to compliance with vehicle manufacturer standards.
• Reduced repair costs while maintaining a high level of quality through the use of a used part.
• Better integration with existing seals and trim elements compared to universal profile aftermarket parts.
