Purpose and vehicle placement

The presented side glass is dedicated to Mercedes vehicles and is located in the front – right side area. This means it works in conjunction with the window regulator mechanism and the passenger-side door frame, ensuring proper cabin sealing and stable movement within the guides.

The placement on the vehicle is factory-defined, which facilitates the selection of the component during body and glass repairs and minimizes the risk of installing incorrect glass for a specific body model.

Technical and functional characteristics

The AS2 side glass belongs to a group of windows with enhanced performance parameters, used as standard equipment in vehicles of this class. The construction ensures:

• appropriate transparency and image clarity in various lighting conditions,
• compatibility with factory seals and door moldings,
• stable seating in the door frame and correct operation with the window regulator.

By maintaining the correct profile and shape, the component helps maintain body tightness, limiting the ingress of water, noise, and air gusts into the cabin interior.

Product condition and service application

The offered glass is a used component, which in practice means it comes from disassembly and may show signs of wear typical for this type of part. This type of component is often chosen as an economical and structurally compliant solution for accident repairs or replacing damaged glass in the front right door.

Using original side glass allows for maintaining the visual consistency of the vehicle and limits potential fitment issues that may occur with non-original parts.

Selection by numbers and compatibility verification

When selecting side glass for Mercedes cars, it is crucial to compare factory markings and mounting parameters with the element currently installed in the vehicle. In case of doubt, it is worth using the part numbers and interchangeable numbers visible in the technical specification to ensure that the glass will work correctly with the door, seals, and lifting mechanism.
