You can retrofit any model of Smokai Smoke Generator to your BBQ / Grill. 

The most popular option for these small chambers is the Smokai Bullet and Classic Smoke Generators.  However, many Smokai Customers have retrofitted the larger models for a ludicrous smoke volume and longer smoke on one load.

To retrofit, you simply need to choose a suitable area on the side of the BBQ / Grill to drill a hole* to accept the smoke outlet tube and attach with the two small bolts provided.  Alternatively, you can rest the Smoke Generator on the side tray (if it's metal) and not use the hardware at all.   

*Hole Diameters Required:
Smokai Bullet and Classic Smoke Generators: 20mm (0.8“)
Smokai Magnum and Monster Smoke Generators: 40mm (1.6“)
