Current holders Dunbarton turned in an impressive performance and on Thursday evening to skip into another final.
They defeated Old Bleach to reach their second successive NIPGL Senior Cup decider.
Played at Falls Bowling Club, Belfast, the Gilford side beat Old Bleach for the third time this season, as all four rinks won in an overall 27 shot victory (88-61).
Waiting in the final will be Ballymena. This will be the third meeting in the season between the two clubs, with a fourth to come on the final day of the campaign.
Ballymena have won both encounters so far in the Irish Cup and League and the Gilford side will need to be on top form if they have any intention of retaining the cup.
