Purpose and Fitment for Mercedes W447

This window has been designed specifically for the Mercedes W447 body, intended for the left rear position of the vehicle. Its precisely shaped edges and correct surface geometry ensure a proper fit within the body frame, leading to stable mounting and maintenance of factory-standard assembly gaps.

This component belongs to the Automotive Glass group, meaning it is prepared for compatibility with original seals, trim strips, and mounting systems used in this model. Such a precise fit minimizes stress on the glass and reduces the likelihood of leaks in the side area.

Technical and Functional Characteristics

The AS2 version of the rear left side window meets the requirements for light transmission and safety for road use. The applied laminated or tempered glass technology (according to AS2 standard) ensures adequate resistance to mechanical damage and controlled material behavior in case of breakage.

Key functional features include:

• precise fit for the factory mounting opening on the left rear of the body,
• maintenance of appropriate structural rigidity within the side body section,
• compatibility with original mounting and sealing elements,
• preservation of proper visibility and driving comfort for rear passengers.

By maintaining parameters consistent with factory specifications, this window allows for seamless integration with existing interior trim and exterior elements such as pillars, moldings, and seals.

Condition, Origin, and Service Application

The offered window is a used part, making it an attractive solution for post-accident repairs, replacement after point damage, or body restoration. Utilizing an original used component helps maintain the vehicle's visual consistency and reduces costs compared to purchasing a new window.

This solution is particularly beneficial when you aim to:

• restore full functionality to the side glazing area,
• maintain the original character of the Mercedes W447 body,
• achieve a reasonable balance between repair costs and the quality of installed components.

Choosing a used window with preserved mounting parameters is a practical approach to repair, allowing for efficient restoration of the vehicle to operational status without compromising essential functional aspects.
