My wife wanted a way to wall mount her embroidery hoops on the wall and set me to the task. This is designed so that the hoops slide over the notches and mount snugly to the base.

This is specifically designed for hoops that go with the following Brother Embroidery Machines:

Brother Machines PE-770 700 750D 780D 800D 1000 1200 1250D

It's 138.5mm long, 78.5mm wide, and 11mm tall at it's highest point.

Hope this helps someone!
