Belvedere remain on course for a first title at this grade in eight years after they saw off a plucky Kilkenny at Stradbrook.
The Dublin side bossed from the off and winger James McKeown got an early try.
Belvedere kept up the pressure and Matthew Oliver went over. Conor Jennings added the extras before Hugh Sexton's superb break led to Cian O'Sullivan's try giving Belvo a 17-0 interval lead.
Kilkenny refused to buckle but, with Anu Awonsui leading them forward, they looked as if they could apply some pressure.
However, poor decision-making saw them miss several chances before Belvo ran in three tries from Jennings, Sam Osborne and Nicky Delamer.
