Foot Control Clamp for the Bernina 7 Series Machines (Black Bobbin)  This does not fit the 4 or 5 series

This was designed to hold your foot control on the open arm so it will not fall while transporting it.  

First put the clamp on the foot control, then place it on the open arm, push down on the pedal and slide to the right  to lock it into the machine.

To take off do it in reverse.
