Purpose and body fitment

The glass has been specifically designed for installation in the front left door of W177 series models, which guarantees a proper fit to the door frame, seals, and guides. The appropriate shape and edge profile allow for correct interaction with factory mirrors, the A-pillar, and trim strips, minimizing the risk of leaks and unwanted wind noise while driving.

By maintaining the original geometry, the installation of the glass does not require any modifications to the door structure or interference with factory mounting points. This is a practical solution for bodywork and paint repairs, where quickly restoring the vehicle's full functionality is key.

Technical characteristics of AS2 glass

The AS2 marking indicates the use of glass with parameters suitable for side windows, ensuring good transparency and compliance with passive safety requirements. This type of glass is designed to minimize the risk of sharp edges in the event of damage, which is important for the protection of the driver and passengers.

Selecting the right type of glass also affects user comfort – the appropriate thickness and material structure help reduce external noise and vibrations transmitted to the cabin interior. This is particularly important in modern designs, where stable acoustic conditions are expected even at higher speeds.

Component condition and use in repairs

The offered glass comes from the used parts market, which allows for a reasonable repair cost while maintaining the manufacturer's original specifications. This type of component is particularly useful for:

• repairs after collisions involving damage to the door area,
• replacing scratched or fogged glass resulting from wear and tear,
• restoring the full functionality of the window lifting mechanism.

In many cases, using an original, used glass helps avoid fitment issues that may occur with parts that do not meet factory specifications. It is a practical solution for workshops and individual users who expect a predictable installation result.

To better understand how to safely and consciously use the second-hand parts market, it is worth reading the article "Used car parts: myths and facts you need to know", which discusses the most common concerns and real benefits of choosing such components.

Support with selection and integration with other elements

When replacing door glass, it is important to consider its interaction with seals, guides, and the window lifting mechanism. A correctly selected component facilitates the adjustment of the glass position relative to the door frame, which translates into the vehicle's tightness and comfort during daily use.
