Option miter
A mitre is standard always 45° respectively with an inside or outside angle. Other angles are possible, please indicate this clearly in the comments field (at checkout).
Option finished side with continuous drip groove
If the head is visible, the side is also best finished. In our case, this implies that the drip groove continues on the side of the capstone. Think here of the beginning or end of a series of capstones on a wall. In this way you can also bridge corners if desired. In this case, please give us all dimensions separately.
