Hi and welcome. You sure have me on this one. I found a bit on the Gerber router, but I have never heard of a Shop Vox. Would you mind adding a picture. Looks like it may be for cutting signs, but I'm in the dark. Many routers are very similar, so you might find another brand that's close enough to use their duct collection accessories. If you have a picture on your computer you can click the rectangular icon just below this, which pops up a window to which you drag and drop your picture from you Windows Explorer. I've looked it up and found software for sign shops, but no devices..
