Purpose and fitment

The presented triangular body glass has been designed specifically for installation in the front right section of the Mercedes W639 model. The construction corresponds to factory dimensions and shape, ensuring that the vehicle's correct side line is maintained, as well as the tightness of the connection with seals and body components.

Its placement in the front zone, on the passenger side, affects side visibility and interior illumination, while the appropriately selected angle and profile of the glass support driving comfort and passive safety.

Technical characteristics of the AS2 glass

The glass marked with the AS2 class meets the requirements for light transmission and safety used in vehicle side glazing. The appropriate glass structure ensures:

• stable performance during temperature changes and typical operational loads,
• an appropriate level of transparency, essential for visibility in the side zone,
• trouble-free installation in factory mounting points.

Thanks to the adherence to factory specifications, the glass works with original seals, moldings, and frames, which reduces the risk of leaks and unwanted stresses in the bodywork.

Benefits of using an original body glass

Choosing a component from the Car windows category dedicated to a specific vehicle model allows for maintaining the structural integrity of the body. Proper fitment translates into:

• correct adhesion to the door or pillar frame without the need for modifications,
• preservation of the factory design line of the side body section,
• reduction of wind noise due to proper alignment with seals.

This solution is particularly beneficial for post-accident repairs or when replacing damaged glazing, where the priority is to maintain parameters close to the factory state.

Condition and practical application

The item comes from a vehicle, which allows for an economical restoration of the glazing efficiency in a Mercedes W639 while maintaining original specifications. Used body glass is a good choice in situations where a reasonable repair cost is important while maintaining compatibility with the body and the factory mounting system.

Before installation, it is recommended to perform a standard verification of the edge condition and prepare the contact surface on the vehicle to ensure proper sealing and durable seating in the frame.
