Connecting a series of cakes and aerial shells together with visco fuse has never been easier. Get that professional looking finale without having to risk getting hurt trying to light multiple fireworks at the same time. A lot of thought and testing went into designing Firework Junction so that we could offer a superior product while still being cost effective. Firework Junction utilizes a series of patent pending ideas which incorporate serrated teeth, living hinges, and snap latches for securely holding 1.8mm to 3mm diameter fuse. The injection molded fuse connector also utilizes a closed tubular design which allows all of the heat and spark from the ignited leader fuse to easily transfer to the firework(s) allowing for more positive ignition. We recommend using 3mm diameter fuse as the main leader fuse.
