Purpose and function of the component

The presented quarter glass operates in the rear right zone of the body, closing off the side door area. It is responsible for:

• maintaining the proper rigidity of the door frame in the rear section,
• preserving the factory geometry of the glazing,
• reducing air turbulence and noise in the cabin,
• providing an aesthetic finish to the window line in the rear part of the vehicle.

Thanks to its factory design, the glass works with original seals, moldings, and mounts, which facilitates installation and helps maintain a consistent look for the entire side body area.

Construction, color, and fitment

The component belongs to the Car windows group and was designed specifically for the Mercedes brand, with the CLA C117 model in mind. The black color of the border area allows for an aesthetic connection with factory seals and trim moldings, creating a uniform, visually organized window line.

Its placement in the rear right part of the vehicle makes the glass crucial for the correct alignment of the door with the body. Proper matching of the glass shape and thickness to the original mounts minimizes the risk of stress, rattling, or leaks after installation.

Benefits of using original, used glass

Using an original part from a dismantled vehicle is a reasonable compromise between quality and repair cost. The used Mercedes CLA C117 Window Glass Door Rear Right O/S Quarter Black allows you to:

• maintain factory fitment and door operation parameters,
• avoid compatibility issues typical of low-quality aftermarket replacements,
• reduce repair costs compared to purchasing a new OEM part.

Use in body repairs and restorations

This quarter glass is suitable both for typical replacement after damage and for more extensive bodywork in the rear of the vehicle. It is particularly useful when:

• mechanical damage to the glass or door frame has occurred,
• it is necessary to replace several glazing elements after a collision,
• you are restoring the vehicle to factory condition after bodywork.

By choosing original glass for your Mercedes, you reduce the risk of problems with door adjustment, leaks, or unsightly differences in the shade and finish of the glazing. This is especially important in premium class cars, where visual consistency and proper component fitment affect the final value of the vehicle.
