The Multi Safe WS3000-2, more safety for your caravan and trailer! On the parking lot, during the journey or at the stopovers. The intelligent lock system ensures that unauthorised coupling or uncoupling is just as perfect as the complete dismantling or replacement of the coupling head, in a single operation. When driving, the trailer is secured to prevent it from coming loose on its own. High quality finish. Milled from a steel block. Drilling protection. TÜV-tested. TÜV acceptance not required.
