It was the first trophy for 11 years for Stuart Glass’ men who seized control in the second quarter and never looked back against a Falkirk side that failed to live up to their tag as favourites.
The Paisley outfit – paced by 25 points and 11 rebounds from Nick Collins – led 41-32 at half-time, executing freely as Fury’s defence folded.
And they eventually raced as much as 75-44 in front with just eight minutes left before a late Falkirk rally managed to salvage some pride.
“We’d been rehearsing for this for weeks and we did nothing here that we hadn’t done in practice,” said a delighted Glass.
“Plus we produced some form which we haven’t always done this season. Basketball’s a funny game. Once one team goes ahead, sometimes heads go down on the other team and you can build a big lead. But I thought we deserved this.”
Roni Gordon had 16 points and 13 rebounds for Falkirk.
Meanwhile, Glasgow Rocks secured the women’s Cup with a 72-60 victory over Edinburgh Kool Kats as Scotland cap Rona Corkindale claimed 23 points, nine rebounds and six assists.
Ailidh Hood added 19 for the Rocks, who were 31-25 in front at the break before Edinburgh cut the gap to two late in the third quarter. But a 13-5 burst eventually saw Glasgow pull decisively away.
