The Tailgate lock is an extension for the lock of a car. By using the Tailgate lock, a space remains open that ensures good ventilation for dogs in parked cars, for example. The Tailgate lid allows more ventilation in a car than when opening the windows. The Tailgate lock can be attached or removed in just a few seconds and the car can be locked in the normal way: either with the central locking or with the key. The Tailgate catcher is available in 3 different lengths.
