This is a hard to fine product. I was very happy to see the stock on the Rocky Mountain site. Not only does it have a good contact patch to protect what ever you’re working on. It has magnets to help it stay attached to the vise.
I wish I would have bought these a long time ago as they help eliminate any damage that can be caused by cranking down the vice on your precious dirt bike components. The magnets aren't the strongest but other than that these are awesome.
