What is the purpose of the roof drain channel clip?

[KiraMarie]

The roof drain channel clip is used to secure the drain channel strip. Below are the specific details about the automobile drain channel: 1. Function: The vehicle body drain channel directs rainwater along the channel to the outside of the car, preventing water from entering the interior of the vehicle body and the internal sheet metal structure. This ensures a comfortable interior space and prevents premature rusting of the body sheet metal due to rainwater. 2. Composition: The drain channel is typically formed by welding the upper section of the rear drain channel plate and the rear combination lamp mounting plate. The top is welded to the roof panel, the sides to the outer side panels, and the lower part to the rear panel. It has a specific cross-sectional shape, forming a water guide channel that runs from the roof along the rear pillar to the bottom of the vehicle body.
