I operate a used car dealer's warehouse. We deal used luxury and sports cars. We are upgrading our warehouse. We have been thinking about making changes in the dock. We have 6 door openings that dock to the trucks. I saw this header dock seal http://www.pentalift.com/us/loading-...dinfoPS100.php that I believe can offer aesthetic look as well as ease of docking the trucks. It forms a gasket seal between the truck and the door. I would like to know if they are durable and efficient. I'd appreciate your suggestions on this.

Thank you .
