This is a very faithful reproduction of the OEM style of Westfalia Pop Top seal. It is made in Germany. The OEM style used a double rubber wiper type seal instead of the generic bulb type that are in the aftermarket kits. They also are bonded at the corners and it is all one piece. If you want a high quality pop top seal that is as close to original as you can get, and will last for many years, this this is the seal you want. We also have an OEM style luggage rack seal which is sold separately.
