[Features] This is a ratchet type rigid rack with a load capacity of 3 tons, used to hold the vehicle after it has been jacked up. You can set the height by simply pulling the saddle up to the position you want it to be placed in the car, and the locking pin prevents it from falling off accidentally. After use, you can easily return it to its lowest position by removing the locking pin and pulling up the handle on the side.
