60 mm rack uprights: 2.3 in vs 2.4 in labels and what fits

Also listed as 2.3 in, 2.4 in, 60 x 60 mm
Short answer
A 60 mm upright is about 2.362 in across, calculated from 25.4 mm per inch, and makers round it differently: Bells of Steel labels its 60 mm tubing 2.3 in and Force USA labels MyRack 2.4 in. Both list 5/8 in holes for attachments, but neither says its parts fit the other's racks. Buy parts that name your rack.

Questions
Is a 2.3 in rack the same size as a 2.4 in rack?
Bells of Steel's 2.3 in and Force USA's 2.4 in labels both describe 60 mm tubing, which calculates to about 2.362 in. The same size does not mean parts cross between the two brands.[1][2][3]
Do 2x2 attachments fit a 60 mm rack?
None of the makers in our sources say so. 2 in calculates to 50.8 mm, so a 2x2 in tube and a 60 mm tube are different sizes; buy parts the maker lists for 60 mm racks.[3]
