mo FAQ 2.2 – Nominal and minimum rail height is 50 inches above the floor?
The nominal (noraml) value as measured from the top of the railhead to the floor is 50″. This is also the minimum, since Free-mo allows grades the max rail height is 62″. There is no spec for 49″, you may have inferred that from the 1 inch adjustable feet. But the adjustable feet are to deal with uneven floors. So a layout can be set at 50″ and kept level over a floor that may be dipping and bumping up to 1″ of uneven-ness.
