How it works:
When you release the handle, the spring pushes down on the lever so it tightens on the different ball sizes.
- The lever inside the space where the tow ball goes has two different grooves to fit both tow ball sizes perfectly.
- Simply push the trailer firmly onto the tow ball, release the handle and lock it on. You can double lock the coupling with a key to prevent it from being stolen when unattended.
