NOTE: In Astrodon part numbers we pronounce the ‘ character (apostrophe) as “prime” and the _ character (underscore) we pronounce as “sub”). So u’2_27R should be read as “u prime 2 sub 27 R”.
However, our dinosaur website software software chokes on ‘ (apostrophes) if they are in a SKU field part number. So we have replaced ‘ with ! in these places. So the above part number (when used in a SKU field) on our website will appear as u!_27R. But it is really u’_27R. Again, this is due to our dinosaur software, but if you Google Astrodon you will find that Astrodon was a dinosaur with star shapes in the fossils…so appropriate, eh? In any event, forgive our software, move on, and be happy.
