Reuse existing screw holes which are 3-1/4 in away from each other (see previous photos, or you can reference the original Ring corner mount if you have one)
Panel height: 3 inch (Last email I said 2-7/8 but just re-measured it today and I believe 3 is the best. See attached pic)
Has a small downward angle (5 degree) so that I can see the rest corner underneath the doorbell (see previous photos)
Projection of the panel: 1/2 inch (just measured it today. See attached pic)
