Description:
For Impaction E12S other than 775,
please purchase QS-QH0042A Mecha Plate (IM775) or
make a Φ3 hole with a width of 30 mm.
If you prepare long screws, you can fix other connectors.
The M3 tap on the 70mm cross member is 30mm wide,
so if you re-open it in the Ф3 hole, you can fix it as shown on the picture.
