Purpose and vehicle placement

The presented fixed quarter side window is designed for installation in the rear left part of the body, within the door or side panel of the Mercedes V177 sedan. This type of glass serves to illuminate the rear passenger cabin while contributing to the rigidity of the side structure and the precise alignment of seals and trim strips.

Placement in the rear of the vehicle means the glass works in conjunction with the rear door and adjacent body elements, which requires maintaining the correct geometry and proper edge profile. As a result, installation is predictable for auto body technicians or glass specialists, and the risk of leaks and unwanted stress is minimized.

Technical characteristics of the AS2 glass

The AS2 marking indicates glass with controlled light transmittance, compliant with requirements for automotive side windows. This type of glass provides:

• an appropriate level of transparency for rear-seat passengers,
• adherence to safety standards regarding impact resistance,
• optical consistency with the other side windows in the vehicle.

Thanks to the factory edge profile and fitment for the specific body version, the glass works with original seals and trim, which facilitates proper installation and reduces the need for additional workshop adjustments.

Benefits of using an original Mercedes window

Choosing an original quarter side window for the Mercedes V177 allows you to maintain the vehicle's factory parameters regarding body rigidity, acoustics, and driving comfort. This element from the Car windows group, designed by the vehicle manufacturer, ensures:

• precise fitment with the door frame and adjacent panels,
• proper compatibility with factory seals and trim,
• uniform color and glass structure compared to the other windows in the car.

The product in used condition is a reasonable compromise between cost and maintaining original manufacturing quality. For many post-accident repairs or restorations, this is a practical solution that allows the vehicle to be restored to full functionality within a controlled budget.

Application in body repairs and restorations

The fixed rear left quarter side window is primarily used for post-collision repairs, replacing damaged glass, or reconstructing the side part of the body. It is an important element in terms of:

• passenger cabin tightness (protection against water and noise),
• passive safety (glass resistance to shattering),
• vehicle side line aesthetics (visual consistency with other windows).

Due to its factory origin, the glass works well with original mounting points and the bonding technology specified by the manufacturer, which facilitates the work of body shops and workshops specializing in glass replacement.
