I needed a way to attach a 1 7/8" vacuum hose to my handbuilt vacuum forming machine. There's starts for 8 mounting holes, but I intentionally left these undersized so you can drill them out for whatever screws you have. Drill a 2" hole in the side of your machine and then bolt this down. Seal with silicone for an airtight seal.
