Brentford are back at Wembley for the first time since 1995 as they beat Exeter City 2-1 in the Johnstone's paint Trophy area final second leg to claim a 3-2 aggregate triumph.
The Bees took full advantage of a woeful first-half performance from Exeter and scored twice within six minutes.
Myles Weston provided the assist for both goals with his first cross finding Sam Saunders at the back post, who rammed the ball into the roof of the net.
Weston then got the better of Richard Duffy before delivering a fine cross that Gary Alexander headed emphatically past former Bees loanee Ben Hamer to make it 2-0 and 3-1 on aggregate.
Brentford were better all over the park and had plenty of opportunities to extend their lead.
Exeter were poor and rarely threatened the home goal, with Daniel Nardiello their only true threat. And it was Nardiello that gave Exeter a small glimmer of hope when he curled a fine shot into the bottom corner deep into stoppage time, but it was too little too late from the Devon side.
