Fox Lodge Women secured a third cup win in a row after a 16-run win against Eglinton in the final at Ballymagorry.
Eglinton were in the ascendancy as early wickets for Jackson had the holders in trouble at 12 for 3.
However skipper Hannah McLaughlin proved the player for the crisis as her 26 saw Fox Lodge recover to 59 for 5 in their ten overs.
22 runs came off the last two overs and they were to prove vital in the final equation.
The Eglinton chase found it difficult to keep up with the required rate due to a combination of the slow outfield and accurate Fox Lodge bowling.
Despite the best efforts of Zara Craig (24*) they finished 14 runs adrift on 45 for 1.
