Intended Use and Fit for Ford Transit Custom

The presented side window has been specifically designed for the Ford Transit Custom, taking into account factory mounting points and door frame shape. Its placement on the vehicle is front, left side, meaning it is installed on the driver's side. This precise fit minimizes the risk of leaks, stress on the glass, and door closing issues after replacement.

The AS2 designation indicates the appropriate light transmission level and compliance with side window requirements, contributing to driving comfort and proper cabin illumination.

Technical and Functional Characteristics

The AS2 side window has been manufactured to meet the standards used by the vehicle manufacturer. The glass construction ensures:

• stable operation within door guides and seals,
• adequate resistance to operational stress,
• proper cooperation with the window lifting mechanism.

By maintaining the correct edge profile, the window works well with seals, helping to reduce wind noise and minimize the risk of water ingress into the door.

Condition of the Part and Benefits of Choosing Used

This product comes from the used car glass category, allowing for reduced repair costs while maintaining original manufacturer specifications. Choosing a part from a dismantled vehicle is a particularly beneficial solution for post-accident repairs and for restoring a vehicle to full functionality after damage to its side glass.

Original used glass is also a good choice for users who want to maintain the visual consistency of all windows in the vehicle – in terms of shade, type of markings, and optical characteristics.

Application in Vehicle Repairs and Restorations

The front left side window is suitable for both standard operational repairs and restoration projects where maintaining the vehicle's factory character is important. For fleet vehicles or heavily used Ford vans, replacing a damaged window with an original used part allows for quick restoration of full driver's door functionality without the need for more expensive solutions.
