Smallest Packard Shutter / Will one fit inside a standard 4x5 Pacemaker lens board?

[Fragomeni]

Can anyone confirm the smallest size Packard shutter available? I've looked at the Packard Shutter website but am having a hard time identifying total outer dimensions of the smallest shutter (may have just overlooked it if its there). I'm wondering if there is one small enough to fit on the inside of a standard Pacemaker lens board (metal with rounded corners) for 4x5.

I’d try emailing Packard. They have always been quick to reply to me.
