Belfast Inst completed a schools double at Ravenhill as tries from Lewis McNamara and Jack Conlin gave them victory over Wallace High – who also lost the provincial Junior decider last week.
There was little between the teams early on in a tight contest before Wallace took the lead with a brilliant try by Conor Guiney, but Andrew Cardosi was just wide with the conversion.
Just before the interval Inst stole a lineout and captain McNamara crashed over before TJ Morris (left) added the extras.
Wallace regained the lead with a Max Trouton try; Cardosi, who had failed with a penalty attempt, missed the conversion.
Inst responded emphatically when Jack Conlin cut through to score, with Morris again on target with the extra points.
Wallace pushed for a winning try late on, but Daniel Soper’s Inst held firm to claim the trophy.
