The product operation is simple: when the door is closed, the triggering pin touches the door frame and lowers the sealing profile vertically until it is pressed under the threshold, for gaps of up 20 mm.
When the door is opened, the triggering pin releases from the door frame and the sealing profile returns vertically inside the cover, allowing the door to open normally.
