This is a German made OEM style luggage rack seal. It is a close copy of the original Westfalia version of this seal. The aftermarket seals we see here in the USA are a generic bulb seal. This one is doesn't use that. It uses a rubber flap to seal the luggage rack to the roof of the van. If you want a seal that is as close to original as you can get, then this is for you. We also sell an OEM style Pop Top Seal separately.
