9-Shot 500-Gram NOAB with 18 Massive Double-Break Effects

Double Barrel (OX5031) from Mad Ox Fireworks is a hard-hitting 9-shot, 500-gram NOAB (Nine on a Board) built around one standout feature: double-break shells. Each of the nine aerial shots produces two separate breaks, delivering an impressive 18 total aerial breaks from a single cake.

With powerful straight-firing launches, huge bursts, and approximately 26–30 seconds of performance, Double Barrel gives fireworks fans the deliberate pacing and oversized appearance expected from a heavyweight NOAB while adding a second break to every shot.

Effects and Performance

Double Barrel sends nine powerful shells straight into the sky, but unlike a traditional single-break NOAB, the action doesn't stop after the first burst. Each shell produces an additional aerial break, resulting in 18 total breaks from only nine launches.

This double-break design gives each launch a more complex appearance and keeps the action developing overhead. Instead of immediately moving to the next tube after a single burst, spectators get a second aerial event from each shot.

9 Shots – 18 Total Breaks

The biggest reason to choose Double Barrel is right in the name.

Its nine double-break shells produce 18 massive breaks, effectively doubling the number of aerial bursts compared with a conventional nine-shot single-break cake.

That makes Double Barrel a great choice for fireworks enthusiasts who enjoy the traditional NOAB firing style but want something more unusual than nine individually spaced single breaks.

Heavyweight NOAB Performance

Double Barrel uses a classic Nine on a Board configuration, with nine large launch tubes arranged on a stable cake base.

The straight-firing design sends the shells approximately 80–100 feet into the air, where the double-break sequences have room to develop. With a runtime of roughly 26–30 seconds, the cake maintains deliberate pacing that allows spectators to appreciate each multi-break launch before the next one rises.

Built for Big Breaks

This isn't a high-shot-count zipper cake designed around speed. Double Barrel is all about the size and impact of individual launches.

The combination of a 500-gram load, nine large tubes, and double-break shell construction makes it especially well suited for sections of a fireworks show where you want large, attention-grabbing aerial bursts rather than hundreds of smaller effects.
