Purpose and fitment

The presented glass is dedicated for installation in the rear right section of the body, specifically in the side door of the Mercedes CLS W218. Its placement in the rear passenger-side door area ensures a consistent window line and the proper operation of the lifting and lowering mechanism.

By using an original component, the correct dimensional tolerances are maintained, which translates into proper sealing, the absence of unwanted wind noise, and stable seating within the guides.

Technical characteristics and color

The glass is manufactured in a green tint, characteristic of many factory Mercedes configurations, allowing for aesthetic matching with other glazing elements. This type of tinting supports driving comfort by reducing the penetration of solar radiation and improving optical conditions inside the vehicle.

The vehicle placement in the rear, right-hand zone requires a component with the appropriate profile and curvature to work seamlessly with factory seals, the door frame, and the window regulator mechanism. Using the correct glass minimizes the risk of stress and cracking resulting from improper fitment.

Condition and benefits of choosing used OEM glass

This item comes from the used original parts segment, meaning it retains the factory geometry and parameters specified by the manufacturer. In practice, this translates into:

• reliable fitment to the door structure and body,
• stable cooperation with existing equipment (guides, seals, regulator),
• the possibility of an economical repair while maintaining OEM standards.

Choosing used glass allows for a significant reduction in repair costs compared to a new component, while maintaining the high quality of workmanship characteristic of the Mercedes brand.

Application in body and side zone repairs

The rear right door glass is a key component for repairs following side collisions, replacing damaged glazing, or during body restoration. A correctly selected element:

• ensures cabin tightness and protection against external factors,
• contributes to passenger passive safety,
• maintains the visual consistency of the vehicle's side profile.

The use of original glass in the rear door area is particularly important in high-end vehicles, where both precision of assembly and the maintenance of acoustic comfort are paramount.

Support in selection and service cost optimization

When selecting the glass, it is worth verifying compatibility with the specific body version and vehicle equipment to ensure that installation proceeds smoothly without the need for additional modifications. In case of doubt, it is helpful to compare the placement parameters on the vehicle and the color with the currently installed windows.
