Purpose and body fitment

The offered window glass is designed specifically for installation in the rear left door section of Mercedes W212 series models. Its placement in this body zone ensures correct guidance along the rails, proper cooperation with the lifting mechanism, and a tight fit against the seals.

As an original component from the manufacturer's range, the glass maintains the correct geometry and thickness, which translates into stable seating in the door frame and reduction of unwanted vibrations when driving at higher speeds.

Characteristics of AS3 tinted glass

The AS3 standard tinted glass provides increased optical comfort for rear-seat passengers. It reduces the intensity of solar radiation, which limits interior heating and improves travel conditions on sunny days.

The darker, black tone of the glass also improves privacy inside the cabin, making it difficult to see into the vehicle from the outside. At the same time, adequate transparency is maintained from the inside, which promotes safe use of the vehicle as intended.

Color scheme and visual consistency

The black finish allows for harmonious matching of the glass to factory moldings, seals, and other elements of the side body line. As a result, replacing a damaged window with this component does not disrupt the visual continuity of the glazing and preserves the characteristic look of the W212 series.

The tinted surface blends well with both light and dark body paints, which is important for maintaining the stylistic consistency of the entire vehicle after repair.

Performance parameters and installation

The glass intended for the rear left part of the vehicle has been prepared for installation in factory mounting points. The appropriate edge profile facilitates seating in the door frame and proper sealing, which is important for protecting the interior from water and outside noise.

As an element from the Car windows category, the product works with original rails and lifting mechanisms, which allows for smooth window operation after installation is complete.

Why choose used OEM glass

Choosing a used original window for a Mercedes allows you to significantly reduce repair costs while maintaining factory fitment parameters and aesthetics. This solution is particularly beneficial for post-accident repairs or replacing damaged glazing in older models, where a reasonable balance between quality and cost is important.
