The Screamer Booster Connector Tubes are cardboard tubes that slip overtop of Screamers and Screamers with Silver Comet and allow for users to add a second-stage pyrotechnic cartridge to create multi-stage pyrotechnic effects.

Any additional 15mm round can be stacked on top for a multi-stage scare effect with the Range Extender Rocket.

Two-stage combinations with Comet Bangers or 15mm Colour Flares can be fired out of any handheld pyrotechnic launcher.
