Unfortunately, the USA-manufactured version of this clamp appears to not have slots for mounting; the VH-13007 (and, for that matter) the GH versions do, however, and make them a better choice for mounting in wood via threaded inserts.
This was the perfect solution to a stabilization issue I had. Easy to install and holds great.
