Rockwell set up a semi-final date with Castletroy with a hard-earned win over Ard Scoil Ris at Clanwilliam Park.
They went into the lead after 24 minutes with a try from Ross Mullane, which JJ Hanrahan converted. Jamie Gavin reduced the arrears by kicking a penalty as Rockwell led 7-3 at the break.
Luke Cahill put Rockwell further ahead with a try midway through the second half and Hanrahan added the conversion.
Three minutes from the end of normal time, Cahill went in for his second try.
