Minifit RITE domes were introduced in 2013 for the Alta, Nera and Ria series products operating on the Inium processor. They are still used on on the Alta2, Nera2 and Ria2 series products launched in March 2015. Minifit domes will not fit original series RITE products. If in doubt about the domes that you require please consult with your dispenser.
