5 XL Protons
This is a variety pack of hardness. The protruding balls all range in the 2" to 4" diameters which means you can't easily loop the device over them. In some cases, you may have to "force majeure" on to them. Once on them, you are good to go but getting on is another story which is why this is our favorite. We consider this set, when used in steep terrain to be the hardest of this line.
Available in USA.
- Base measures approximately 5" x 5"
- Protrudes from the wall 3-1/2"
