Rangers finished top in style by dispatching Egremont after a gruelling season, with returning recruit Joe Roper getting the scoring under way and kicking the last conversion to end the game 36-0.
It was another taste of success for a team which has largely come through the ranks together, with the younger end of the side winning trebles at both under-12s and under-14s levels in the past.
Despite the scoreline Seaton were made to work for the win and the trophy, although Roper scooted from half-back and scored to get them going early on.
He went over right of the sticks after Owen Durham ripped the ball one-on-one and Levi Wallbanks converted.
Billy Challenger crossed the whitewash from a penalty, with Wallbanks again converting, before Todd Wilkinson made the most of a gap to make it 16-0 at half-time.
Not long after the restart Malik Steele was next to crash over the whitewash, with the ball worked left then back across before Roper providing a flat ball for Steele to finish before adding the conversion.
Great hands then got the ball out to Wallbanks on the right and he marauded down the wing to score an unconverted try.
Possibly the pick of the tries was a fantastic individual effort from Ben Postlethwaite from his own 40, dancing through the Mont to score wide left, although the conversion was again missed.
Egremont were down to 12 men thanks to a yellow card and Rangers capitalised with one final try via Owen Durham, who burst through before Roper converted and celebrations ensued.
