I'm making some modifications for a friend's pedalboard and I'm thinking he's going to need an ISO 5 to compliment his PP2. I've never used one before, but assume that they come with similar mounting ears for pedaltrain boards? If this assumption is correct, would someone be able to make a quick measurement of the total length the ISO takes up mounted on the underside of a pedaltrain board, INCLUDING the rack ears. So a measurement from ear edge to ear edge. He's got some pretty crowded real estate under there and I want to make sure I can fit it ahead of buying one... Please and thanks!
