Purpose and fitment for Ford Transit Custom Mk8

The presented glass has been designed specifically for installation in the front left door wing of the Ford Transit Custom Mk8. Proper placement on the vehicle guarantees correct geometry, compatibility with guides, and proper operation with the window lifting mechanism.

Thanks to its factory origin from the Ford OE line, key parameters are maintained, such as:

• correct shape and glass bending radii,
• appropriate thickness and type of glazing compliant with the AS2 standard,
• precise fit with seals and the door frame.

Such fitment reduces the risk of leaks, rattles, or excessive stress on the glass after installation.

Technical characteristics of AS2 glass

The AS2 door glass is a solution used as standard in modern commercial vehicles. This designation relates to a specific level of light transmittance and safety parameters that meet homologation requirements for side windows.

In practice, this means that the glass:

• ensures proper visibility for the driver and passenger,
• is adapted for use as a side window in the front doors,
• maintains proper optical parameters, minimizing image distortion.

As a result, driving comfort and compliance with technical inspection requirements are maintained after replacement.

Benefits of choosing original used glass

Choosing original used Ford glass is a reasonable compromise between cost and quality. A component sourced from vehicle dismantling retains factory mounting parameters while allowing for a significant reduction in repair budget compared to a new part.

The main advantages of this solution include:

• retention of the factory standard of workmanship and fitment,
• no need for modifications to mounts or guides,
• attractive price-to-functionality ratio, especially in accident and fleet repairs.
