The choice between Bosch and Item type profiles is probably only relevant in Europe. You want the 8mm opening for 3030s so B-type is correct. I also used B-type for 2020s. Make sure your brackets, fasteners etc match the profiles.

The link in the BOM shows a profile with an 8mm opening if you're in doubt.
