Depending on how old your software is the Hoop Tech could be in your software. In OS go to Tools and then to Hoop Set up. Under the custom hoop list see if it says Hoop Tech. It will list each size hoop by its measurements. Hoop Tech have been in the list for several years. The Hoop Tech has a raised part at the back of the carriage so be careful to watch that you always shut the clamp when leaving the machine or remove it after each use. If that raised area hits to needle area you will need a tech to come out to fix it. They work great but need to be aware of this issue. We also used a permanent marker on the frames to mark the sizes.
