Purpose and body fitment

The presented triangular side window has been designed specifically for installation in the front right section of the Mercedes Vito W639 body. Its placement in this area of the body supports proper driver visibility in the mirror and pillar zone, and also helps reduce air turbulence at higher speeds. The window construction is adapted to the factory door frame, which facilitates installation and allows for maintaining the vehicle's original side line.

Technical characteristics of AS2 glass

Glass marked with the AS2 grade meets the requirements for light transmission and safety in side applications. This type of window is sufficiently mechanically durable while providing comfortable visibility in daily use. The use of the correct type of glass in this part of the body is important both for passive safety and for compliance with homologation regulations.

Benefits of using an original side window

Choosing an original triangular side window for the Mercedes Vito W639 allows for maintaining the structural integrity of the body and proper fitment with seals and trim strips. This reduces the risk of unwanted air noise, leaks, or stress on the door frame. Precise fitment to the specific model translates into stable window seating and lower loads on mounting elements during operation.

Used condition – an informed technical choice

The offered window comes from the secondary market, which allows for reducing repair costs while maintaining the functionality required for daily use. For many fleet users and workshops specializing in the service of commercial vehicles, this is a reasonable compromise between price and performance parameters. Selecting the right side window is important not only for aesthetic reasons but also for practical ones – it affects driving comfort, cabin noise levels, and protection of the interior against external factors.
