Intended Use and Fitment

The presented window is dedicated to the rear left side of the vehicle, guaranteeing a precise fit to the door frame and factory seals. Its construction corresponds to the original solutions used in Mercedes W221 models, ensuring compatibility with factory window channels, regulators, and mounting elements.

The green tint has been selected to maintain a uniform appearance of the glazing throughout the vehicle, without color discrepancies visible from the outside. This is particularly important when replacing a single element while the other windows remain original.

Technical Properties of the Window

The window meets the AS2 standard, which signifies an appropriate level of light transmission and radiation filtration, in line with requirements for side windows. The applied green glass reduces interior heating and improves driving comfort, while not hindering visibility for the driver or passengers.

The component has been designed to work with the factory window lifting mechanism, maintaining the correct edge geometry and glass thickness. This allows for smooth movement within the channels, without excessive resistance or risk of damage to the seals.

Condition and Benefits of Choosing a Used Part

The window comes from the secondary market, which helps reduce repair costs while maintaining the original manufacturer's specifications. Choosing a used part is an economically beneficial solution, as well as one that ensures proper fitment – the element is compliant with factory installation and finishing standards.

During installation, it is recommended to use appropriate tools and check the condition of the window channels and seals to fully utilize the potential of this window and ensure watertightness and proper operation of the lifting mechanism.

How to Safely Assemble Used Car Windows

When selecting side windows for a specific model, it is worth paying attention to their placement on the vehicle, the glass color, and compatibility with door equipment. It can be helpful to use part numbers and interchangeable numbers, which facilitate the identification of the correct element in catalogs and search engines.
