It secures the flexible aeroskirt panel to the trailer sub‑frame and is designed to be spring‑loaded, allowing the skirt to flex upon contact with curbs or road obstacles without sustaining major damage. Brackets can become bent, cracked, or broken after years of service and repeated impacts; replacing worn brackets helps maintain aerodynamic performance and keeps the skirt system functional.
