Stephen Archer and Simon Zebo were the first half try scorers with Scott Deasy converting both and adding two penalties for a 20-3 interval lead.
Lifeimi Mafi extended the lead three minutes after the restart with a try under the posts and right at the death Dave Kilcoyne scored his side's fourth try to complete a most satisfactory afternoon for the home side.
