Purpose and function of the strip

The described window sealing strip is mounted on the exterior, in the rear right part of the body, in the passenger door area. Its purpose is to:

• provide stable guidance for the window edge in the rear right door,
• limit the ingress of water and contaminants into the door interior,
• provide an aesthetic finish to the glazing line on the side of the body.

The chrome surface of the strip creates a visually consistent band with other decorative elements, which helps maintain the characteristic, elegant appearance of the Mercedes body.

Exterior finish and color

The strip features an exterior finish in Chrome, which highlights the window line and gives the side of the body a more orderly, modern character. The chrome surface blends well with both light and dark paint colors, as well as other decorative elements such as window frames or door sill strips.

Thanks to the use of an original profile, the strip maintains the correct geometry of adhesion to the glass and door panel, which facilitates installation and minimizes the risk of gaps and leaks in the window edge zone.

Installation characteristics

The component has been designed specifically for the rear right side of the body in the W177 series, which means its shape, length, and mounting method are adapted to factory mounting points. In practice, this translates into:

• secure seating of the strip in the door slot,
• proper guidance of the window edge during opening and closing,
• maintaining an even line of chrome along the entire length of the vehicle's side.

The used nature of the component makes it a cost-effective solution while maintaining original geometry and compatibility with the factory door construction.

Practical application and benefits

Using this window sealing strip allows you to restore the proper appearance and functionality of the side of the body after mechanical damage, corrosion, or wear and tear. Replacing the component is particularly recommended when:

• leaks or excessive wind noise appear at the window edge,
• the chrome surface is clearly scratched or peeling,
• the strip does not adhere evenly to the glass or door panel.

By using an original strip from the Protective and decorative strips group, you maintain the stylistic consistency of the body and proper window guidance in the rear right door.
