Purpose and fitment

The presented window glass is designed as a component mounted in the front left door of the W221 body, which guarantees proper fitment to the guides, seals, and the window lifting mechanism. This ensures the correct geometry of the glass relative to the door frame, which reduces the risk of leaks, wind noise, and closing issues.

The blue tint of the glass is characteristic of many equipment configurations of this generation of the Mercedes S-Class, which is why replacing it with this type of glass allows you to maintain the visual consistency of all windows in the vehicle. This solution is particularly beneficial for post-accident repairs or when replacing a single component after mechanical damage.

Technical characteristics of AS2 glass

Glass marked with the AS2 class meets rigorous safety and light transmission requirements for side windows. This means that the glass provides adequate visibility while filtering part of the radiation, improving visual comfort for the driver and passengers. The glass construction is adapted to work in the standard door guides of the Mercedes W221, which facilitates installation and subsequent operation.

As an item from the Car windows category, the product is made of tempered safety glass, which, in the event of damage, breaks into small fragments with limited edge sharpness. This characteristic reduces the risk of serious injury in the event of a collision or a strong impact on the glass.

Condition, functionality, and application

The glass comes from dismantling, which allows you to combine original fitment with a more favorable purchase cost compared to a new component. The used component retains its factory geometry, so after proper installation, it is possible to achieve tightness and operation of the lifting mechanism at a level similar to factory assembly.

The element will work well both for post-accident repairs and for replacing glass damaged by vandalism, chips, or cracks resulting from use. The use of an original glass dedicated to the W221 limits the need for additional modifications and adjustments, which shortens service time and reduces the risk of future operational problems.

Benefits of choosing an original used glass

Choosing an original door glass for the Mercedes W221 allows you to maintain the optical consistency of all windows, proper fitment to seals, and compatibility with factory lifting mechanisms. This is especially important in premium class cars, where the precision of fit affects cabin noise levels, driving comfort, and the overall impression of quality.
