This component from the Door Seals group is designed to withstand variable weather conditions and mechanical stresses resulting from frequent door opening and window movement. Using this strip allows for the restoration of proper window operation after body repairs or window replacement, and also helps reduce fogging and moisture inside the door.

Installation Characteristics and Application Area

The seal is designed for installation in the front right door, in the area where the window meets the door frame. Its construction, tailored to the specific body, facilitates correct positioning of the strip in the factory mounting points. Vehicle Placement: Front – Right Side clearly identifies the correct installation area and helps avoid errors in part selection.

The product is a used original component from a vehicle, meaning it retains its factory geometry and profile. For the user, this translates to the ability to restore the original window operating parameters without the need to fit aftermarket parts of uncertain specifications.
