Purpose and body fitment

The offered window is designed specifically for the front left door in Mercedes W177 family models, which translates into a precise fit for the door frame and window regulator guides. The construction complies with the AS2 marking standard, ensuring appropriate light transmission and comfort during daily use.

The geometry of the glass is adapted to the factory shape of the body, which facilitates installation in existing seals and the window regulator mechanism. As a result, this element can be used both for replacement after mechanical damage and for post-accident repairs of the vehicle's front left side.

Function, safety, and driving comfort

The front side window on the driver's side plays a key role in terms of visibility and protection against external factors. The AS2-type glass provides:

• appropriate transparency for safe vehicle operation,
• stable performance in the guides during repeated raising and lowering,
• consistency with the vehicle's other glazing in terms of color and optical characteristics.

A properly selected side window reduces air turbulence at higher speeds, improves cabin acoustics, and supports the proper functioning of door sealing systems.

Installation characteristics

The element is intended for installation in the front left part of the vehicle, within the standard window regulator mechanism used in the Mercedes W177. The glass construction allows for compatibility with factory:

• door guides and seals,
• door frame and trim strips,
• window regulator mechanism (manual or electric – according to the car's configuration).

Proper dimensional fitment minimizes the need for additional modifications and allows for efficient installation in workshop or service conditions.

Condition and use in repairs

The window is a used part, which makes it an attractive solution for economic repairs, especially in cases of damage resulting from collisions or glass breakage. Choosing original glazing from dismantling allows you to maintain the factory character of the body and the fitment to other bodywork elements.

Such a solution is often chosen by workshops specializing in post-accident repairs, where both compliance with the vehicle's construction and optimization of material costs are important.
