Application and fitment for Ford Focus Mk2

The presented window is designed specifically for the Ford Focus Mk2 model, intended for the front passenger side. Thanks to its factory profile and precise bending radius, the glass works correctly with the guides, seals, and window regulator mechanism, which reduces the risk of jamming and leaks.

The original door glass construction guarantees proper adhesion to the door frame, which is important for both acoustic sealing and protection against water and contaminants. This is particularly significant when operating the car in urban conditions and on longer journeys.

Characteristics of AS2 green glass

AS2 green glass is a standard used in many Ford models, providing a balanced level of light transmission and thermal comfort. This type of window:

• reduces interior heating on sunny days,
• ensures clear visibility without excessive darkening,
• maintains a consistent appearance with the other side windows in the vehicle.

As a result, replacing a damaged component with a window of the same optical characteristics allows for maintaining a uniform body appearance and proper performance parameters.

Benefits of choosing an original used window

Choosing an original Ford door window from the secondary market is a sensible solution for drivers who want to combine cost control with maintaining factory fitment. A used OEM component usually works better with existing guides and seals than aftermarket replacements with a universal profile.

The Ford Focus Mk2 Door Window Glass Front Right O/S AS2 Green, as a used part, allows for significantly lowering the cost of repairs after a collision or mechanical damage, while maintaining compliance with the vehicle's factory specifications.

Practical installation tips

When replacing the front door window, it is worth paying attention to the correct positioning of the glass in the guides and the condition of accompanying elements, such as seals, sliders, and window regulator mounts. Precise adjustment minimizes the risk of rattling, play, and uneven closing.

Installation in a specialized workshop or by an experienced mechanic is recommended, which allows for maintaining the integrity of the door system and proper alignment with the bodywork.
