Simple holder for cutting pliers so u don't have to watch them being all over the place. Slides simply into the place. The fit may be a bit hard but it works, use just a little bit of force. Once in, you should be able to move it without any bigger effort.
You might get away without supports, but i suggest to use them. See pictures above to see the right orientation for the best result.
