Purpose and function of the component

The presented trim is designed for installation on the right side of the vehicle, in the sliding side door entrance area. It is responsible for:

• protecting the sill against scratches and scuffs during entry and exit,
• a neat, factory-style finish of the body edge,
• providing a stable footing during frequent use of the sliding doors.

Due to its design, which complies with the manufacturer's specifications, the sliding side door entrance trim panel cover maintains the correct geometry and fitment with other side panels.

Original origin and fitment for Mercedes W639

The component comes from the Mercedes brand, which ensures the quality standards typical of OEM parts. The trim construction is adapted to the specific body structure of the W639, in particular to:

• the sill profile in the sliding door area,
• factory-provided mounting points on the bodywork,
• the styling line of the side body section.

Such precise fitment translates into secure installation without modifications and a consistent appearance with other trim elements.

Performance characteristics and installation

The sill trim is intended for installation on the right side of the vehicle, in the location factory-designated by the manufacturer. This allows for:

• installation using existing mounting points,
• maintaining the correct gap between the sill and the sliding door,
• seamless compatibility with seals and other side panels.

The used condition of the part makes it a cost-effective solution while maintaining original geometry and compatibility with the Mercedes W639 body.
