Q
Gran, guest, from TN, United States, asked on September 17, 2018

Do you install with the prongs or are there flat spaces like an A2?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on November 24, 2018

There are no flats. You should still be installing and tightening from the base and not the prongs.
