Purpose and Fitment

The rear right side window has been designed specifically for the Mercedes S-Class W221 body, taking into account the geometry of the doors, seals, and guides. Its placement on the vehicle is rear, right side, which guarantees compliance with the factory body layout and correct seating in the door frame.

By maintaining the original curvature and dimensions, the window works with the factory window regulator, ensuring smooth opening and closing, and proper adhesion to the seals, which reduces aerodynamic noise and the risk of leaks.

Technical Characteristics of the Window

The element belongs to the Automotive Glass group, meaning it meets the requirements for rigidity, stress resistance, and compatibility with the door structure. The window is designed for installation in factory mounting points, without the need for bodywork modifications or interference with the guides.

The edge geometry is adapted to standard seals and trim, which facilitates installation and allows for maintaining an aesthetic, cohesive look of the side body. The appropriately selected thickness and type of glass contribute to acoustic comfort inside the cabin and the stability of the window while driving.

Benefits of Using an Original Rear Right Window

• Factory fit for the Mercedes W221 body on the rear right side.

• Proper adhesion to seals, reducing noise and the risk of leaks.
• Cohesive appearance of the side window line after repair or replacement.

Using an original window helps maintain the door rigidity designed by the manufacturer and the correct operation of the entire window assembly, which is important for both comfort and the durability of the mechanisms.

Application in Repairs and Restorations

The rear right side window is suitable for accident repairs, replacement after mechanical damage, or during the restoration of a Mercedes W221 body. It is a practical solution when you want to maintain the original vehicle specifications without compromising on fit and functionality.
