This problem occurs for some jumpers and doesn’t affect other jumpers where the rope slides down the handles for certain movements.
Here is a quick solution:
- Remove the Rubber End Caps from the rope and cut the end off with scissors, so they are now rubber tubes.
- Remove the Length Adjusting Screw and the Handle from the rope.
- Slide the Rubber tube onto the rope, and then the handle so it is against the rubber tube and then the adjusting screw.
- This will provide enough resistance to stop the rope sliding down the handles.
You may now wish to cover the ends of the rope with electrical tape to prevent scratches from the bare wire.
