TOP-RAIL® was the first system for vehicles without a serial gutter on the world market. The complex use and the advantages that TOP-RAIL® offers have not been reached by any other similar product.
The spoiler set for the TOP-RAIL® rain gutter perfectly diverts the rainwater coming from the roof. No rainwater can run through between the aluminium profile and the spoiler. Thanks to this, it cannot overflow.
When stationary, the rainwater runs off via the windscreen and not via the A-pillar of the doors.
A matching spoiler set is mandatory for TÜV (MOT) approval!
