Purpose and compatibility for Ford Focus Mk3

The presented glass has been designed specifically for the front right door of the five-door body style of the third-generation Ford Focus. This ensures the correct curvature, thickness, and edge lines, which translates into proper operation with the window regulator mechanism, seals, and door frame. As a result, after installation, the glass moves smoothly in the guides, and water and noise sealing remain at the levels intended by the manufacturer.

Technical characteristics of AS2 glass

Glass marked with the AS2 rating meets the requirements for light transmission and mechanical resistance for side windows in passenger cars. This type of glass provides:

• an appropriate level of clarity, essential for visibility in mirrors and during maneuvers,
• controlled impact resistance in daily use,
• a safe breakage pattern, reducing the risk of serious injury.

By maintaining the factory glass parameters, the driver and passenger receive stable visibility conditions, and the door system maintains its proper operating parameters.

Vehicle placement and installation aspects

The component is intended for installation in the front – right side of the vehicle zone, which is important both when selecting parts and when planning service work. Proper placement on the vehicle facilitates:

• selection of compatible seals and guides,
• correct alignment of the glass relative to the door frame,
• maintenance of proper operation of the window regulator mechanism.

Due to its factory origin, the glass works with original mounts and adjustment elements, which shortens installation time and reduces the risk of needing additional modifications.

Benefits of using original Ford glass

Choosing an original door window for the Ford Focus Mk3 primarily means certainty of fit and the preservation of the factory body geometry. The user gains:

• a consistent look for the vehicle's side profile,
• proper cooperation with seals and trim strips,
• stable acoustic parameters inside the cabin.

The product from the Car windows category is the right choice for replacement after damage when you want to maintain the original functional properties of the vehicle.

How to verify compatibility by OEM number and VIN

To ensure that the glass will be fully compatible with your Ford, it is worth comparing the OEM number and data from the vehicle's VIN before purchasing.
