Abstract: A weatherstrip for a vehicle having a seal gap defined by a door and a door flange surrounding a door opening is provided. The weatherstrip includes a magnet positioned around the door opening in the seal gap such that the door is magnetically secured thereto when the door is closed. The weatherstrip also includes a resilient web having a pocket in which the magnet is mounted and a gripping member having a channel for straddling the door flange. The gripping member has at least one rib on an internal wall of the channel for affixing the gripping member to the door flange. Also, the gripping member is integrally joined to the web to provide a weatherstrip which substantially seals the seal gap when the door is closed.
