I have a Audi A6 Avant with rail system in the luggage compartment.
Previously I had a boot tub made of plastic with an anti-slip coating in the middle of
Trunk with rail system, this is narrower than the trunk itself and even slip back and forth in the trunk, in addition to little black pieces of rubber detach from the plastic tub (after only one year) which then everywhere hanging on the charge.
So I've decided to offer you the rubber mat, this is absolutely perfect fit for my car.
It is exactly as wide as the trunk and even covers the rails from the sliding Zurhaken can remain in the tracks it's specially provided bulges!
The cargo is optimally protected by the patterned rubber surface to prevent slipping, the raised edge ensures that liquids etc. Not in the vehicle carpet can run.
All in all an absolute buy recommendation! It just takes a little until the rubber smell is gone, but is not bad!
