When used as a panic threshold, the door would be an outswinging door. The interior side of the door would be 1-7/8" from the interior edge of the threshold. If the door were 1-3/4" thick, the exterior side of the door would be 1-3/8" from the exterior edge of the threshold.
Of course, there is no reason why this could not be used on an inswinging door, but this door could not be used as a panic door.
