As with the large 8-way escape, the generous dimensions of this escape mean you won't have to be precise in cutting the hole in your board. The long exit run means there is less likelihood of re-entry. A very popular escape in Europe.
Note that there needs to be plenty of room below the escape board for the exiting bees to easily leave the honey supers. Severe congestion near the escape exits make clearing the honey supers problematical. So if not using a deep 50mm escape board, a spacer rim needs to be added below the honey supers and the escape board.
