Purpose and fitment

The frame has been designed specifically for W212 series models, taking into account factory mounting points and door geometry. Its placement in the rear zone on the right side of the body allows for precise fitment to the door shape and proper window guidance within the tracks.

The black color facilitates integration with most styling configurations, both in versions with dark and lighter trim strips. As a result, the component fits well into the side body line without the need for additional modifications.

Technical and functional characteristics

The frame plays a key role in stabilizing the window and sealing the contact area between the glass and the door. The properly profiled construction supports:

• proper window guidance during opening and closing,
• maintaining a seal at the contact point between the window and the door,
• reducing vibrations and unwanted noises while driving.

As a body component from the Doors and door panels group, the frame works in conjunction with seals, the window lifting mechanism, and the door skin, creating a cohesive structural system.

Condition of the component and benefits of use

The offered frame is in used condition, which allows for an economical replacement of a damaged part while maintaining proper fitment to the factory door construction. Compared to non-OEM replacements, using an original frame helps maintain the correct window guidance geometry and proper interaction with existing seals.

Replacing the frame is particularly recommended in situations where there are problems with the window closing, leaks in the rear door area, or visible mechanical damage in the window frame area.

Practical installation tips

Before installation, it is worth verifying the component's compatibility with the vehicle based on the manufacturer's markings and vehicle data. Installation in a workshop environment is recommended, using appropriate tools for removing door upholstery and the window mechanism to avoid damaging other components.

After installing the frame, check the smoothness of the window operation, even adhesion to the seals, and the absence of additional noise while driving. A correctly installed component contributes to maintaining acoustic comfort and visual consistency of the side body section.
