Purpose and fitment for Ford Focus Mk3

The offered window is designed specifically for the 5-door Ford Focus Mk3 body style, intended for the front left side. This means full compatibility with the guides, seals, and window regulator in the driver's door, without the need for any modifications to the body or mounting elements. Its original Ford origin ensures the preservation of factory optical and mechanical parameters, which is essential for both visibility and proper interaction with the exterior mirror and window adjustment systems.

Technical characteristics of the AS2 glass

The AS2 glass class indicates tempered glass with controlled light transmission, intended for side body zones. This type of glass provides:

• stable optical parameters, reducing image distortion while driving,
• increased resistance to mechanical and thermal stress,
• a safe breakage pattern into small fragments in the event of damage. As a result, the glass works well with factory door seals, maintaining proper rigidity and tightness under typical urban and extra-urban operating conditions.

Condition, functionality, and application

This item comes from the used Car windows category, which allows for combining reasonable costs with the preservation of the manufacturer's original specifications. The glass is intended for direct installation in place of the factory component, using standard mounting points and existing guides. Replacing a damaged or scratched side window with an original Ford component allows for restoring the correct operation of the lifting mechanism, reducing wind noise, and improving acoustic comfort inside the cabin. It is a practical solution for both post-accident repairs and the operational replacement of worn glazing elements.

Benefits of using an original Ford window

Using an original side window in a Ford Focus Mk3 brings a number of technical and practical advantages:

• Factory fit – maintaining the correct glass geometry relative to the door frame and seals, which facilitates adjustment and minimizes the risk of leaks.
• Consistency with other glazing – uniform tint and glass characteristics compared to the other windows in the vehicle.
• Hassle-free installation – the ability to use standard mounting elements and guides without additional modifications. This solution is particularly beneficial for workshops, body shops, and users who expect a predictable repair result and the preservation of the vehicle's factory standard.
