With both sides missing a number of regulars it was the home side who progressed to the semi finals with a combative performance by 3-1.
Young Elliott Rea hit the post for the visitors on 10 minutes after being well set up by Colin Cunningham and the home side responded on the break with the goalkeeper adjudged to have committed a foul outside his area but the resulting free kick was fired over the bar.
Cunningham was then chopped down at least 3 times outside the area but once again the free kick was wasted.
Jake Redpath who had been carrying an injury was then replaced by Davy Gray who went on to have a very good all round game as both sides went in all square at half time.
On 55 minutes Banbridge went in front when Chambers won yet another header to set up the chance which was duly dispatched into the bottom corner.
Rea was then replaced with a more attacking option in the form of James Mitchell making his first team debut and he was on the score sheet immediately with a deflected shot and Cunningham almost put the visitors in the lead but his shot rebounded to safety off the cross bar.
Another great run by Gray found Mitchell but his shot was easily saved and shortly after against the run of play with another long ball over the top Banbridge went in front again.
Young Neil Allen became the second reserve team player to make his debut when he came on for adam Patterson but in the final minute after a defensive lapse Banbridge wrapped up the victory to put them into the semi finals.
