Purpose and vehicle fitment

The presented window glass is intended for installation in the rear left door of the vehicle, which corresponds to the factory placement in the Mercedes W177 body. The component has been designed as part of the original side structure, ensuring it maintains the correct body line, airtightness, and compatibility with seals, guides, and the window lifting mechanism.

As an element from the Car windows category, the glass works with the factory door opening and closing system and does not require any modifications to the mounts or changes to the door frame structure. This solution is particularly beneficial for professional body and glass repairs, where dimensional repeatability and compliance with manufacturer documentation are essential.

Technical and functional characteristics

The rear left window glass for the Mercedes W177 is manufactured to the AS2 marking standard, which in practice means the appropriate level of tinting and light filtration consistent with requirements for side windows. The design of the pane is adapted for operation within a moving lifting mechanism, ensuring smooth sliding in the guides and stable support within the seals.

This solution allows for:

• maintaining proper side visibility for rear-seat passengers,
• correct cooperation with factory seals and trim strips,
• maintaining body tightness against water and external noise.

Due to the preservation of the original geometry, the glass works well with the bodywork, which is important for the precise alignment of the door relative to the body and avoiding stress on the glass.

Application in repairs and renovations

The used rear left window glass for the Mercedes W177 is suitable for body and paint workshops, service centers specializing in the Mercedes brand, and individual users who want to restore full door functionality after a collision or mechanical damage. Replacing the glass itself is often more cost-effective than a complete door replacement, while maintaining the appropriate standard of safety and comfort.
