Dunstablians warmed up for their league season with a 21-7 victory against Enfield Ignatians at the weekend.
The hosts were in front when Stuart Hall went over, with Kevin Boland converting, while the same pair then repeated the feat to make it 14-0.
Enfield hit back with a penalty try before Boland set off on a long distance effort to touch down and also add the extras himself.
