Purpose and fitment for Ford Focus Mk2

The described rear right side window is designed specifically for the Ford Focus Mk2 model, which ensures a precise fit to the factory window opening and proper compatibility with seals and mounting strips. Its placement in the rear zone, on the passenger side, allows for maintaining a consistent side body line and proper structural rigidity of the chassis.

Its original Ford OE origin means that the geometry, glass thickness, and edge finishing method comply with the standard used in original equipment. As a result, the glass is suitable both for post-accident repairs and for replacing a worn or damaged element in a daily-driven vehicle.

AS2 glass characteristics and function in the bodywork

Glass marked with the AS2 class is a solution used in side and rear glazing, providing good visibility while limiting excessive interior heating. This type of glass helps maintain cabin thermal comfort and improves passive safety, as it is designed to dissipate impact energy in a controlled manner in the event of damage.

In the rear part of the body, the quarter glass performs several important functions:

• it stabilizes the structure of the side body,
• it provides passengers with additional interior lighting,
• it influences the aerodynamics and acoustics of the cabin,
• it maintains a consistent appearance of the vehicle's side line.

By maintaining the factory AS2 glass parameters, replacing a damaged element with an original glass from dismantling allows for the restoration of the vehicle's original functional and visual properties.

Condition, origin, and benefits of choosing used glass

The item comes from dismantling and is offered as used side glass, which represents a reasonable compromise between repair costs and maintaining original Ford quality. In practice, this means the possibility of restoring full glazing functionality at lower costs than purchasing new glass from an authorized network.

Choosing original glass from dismantling is particularly beneficial for body and paint repairs, where compliance with factory specifications and dimensional repeatability are crucial. This type of component helps avoid problems with leaks, excessive wind noise, or improper seal adhesion, which can occur with low-quality parts.

Installation and practical application

The Ford Focus Mk2 side quarter window glass is intended for installation in the rear zone, on the right side of the vehicle, in the place of the factory quarter glazing. With proper installation using appropriate seals and mounts, it is possible to restore the original tightness and aesthetics of the bodywork.

Due to its precise fit for the specific model, the glass will work well both in professional body and paint workshops and in specialized services dealing with car glass replacement. Factory geometry facilitates the installation process and minimizes the risk of needing additional modifications.
