This 'Drum Smoker' adapter is in the teardrop inlet shape favoured by brands such as Gateway.
It's solidly made of Stainless Steel, the base is actually 5mm thick to ensure tight side to side contact with the air inlet.
Simply unscrew your current teardrop inlet vent and replace with the Smartfire vent.
- It includes a red plastic plug to seal the adaptor and keep the bugs and weather out when not in use. It's heat resistant to 70C/160F, so recommend to let the fire die down via the exhaust before using it.
