Lifting Cups and Back Pressure Caps

2” Lifting Cups-are used in the Pro Launcher. This device is positioned in the bottom of the Pro Launcher Barrel. The 2” Lifting Cup aids in the projection of the Pro Streamers & Pro Fetti once the CO2 cartridge has been pierced. 

Back Pressure Caps-are used in the Pro Launcher. This device is positioned on the top of the Pro Launcher Barrel. For optimum use of the Back Pressure effect, a piece of tape should be used to secure the cap to the barrel. 

2” Tethered Lifting Cup- is used in the Pro Launcher instead of the disposable Lifting Cup. This device is reusable for the approximately 10 shots and then it should be replaced.
