The Unitec 10019 Park stop mat a total delight. It needs no fixing measures. They are placed just on the garage floor, then moves -As gewohnt- in the garage, travels over the first Hulper and then lands in the valley between the first and second Hulper and you know then that you came to the right place to hold , All this must be done with a modest pace, of course, then a car and nothing happens and the vehicle is then securely at the desired location in the garage.
