• the ability to disassemble and assemble using standard workshop tools,
• no need for interference with the door structure,
• easier diagnostics of potential faults within the window lifting mechanism.

The product is suitable for both professional service centers and independent workshops, where repeatability of installation and compliance with factory solutions are valued.
