IQ110 BBQ Temperature Regulator Kit with Aluminum Hose Barb and Flange Pit Adapters for Gateway Drum Smoker (55 Gal) and Other BBQ Drum Smokers with Intake Flange or 1" Ball Valve As seen on Good Eats "Right on Que". Alton Brown said: "It's so cool!!" Foods cook in a smoky environment that is naturally moist resulting in foods that are juicy, fall-off-the-bone tender, and simply delicious. Keeps a UDS cooking at 225 degrees on one load of charcoal for up to 12 hours! Fits pits with a 1" female NPT port such as Rebel Smokers, Stumps Smokers, Ugly Drum Smokers (drums), and many home made cookers. Everything included in kit for operation from AC power; operates from 12VDC cigarette lighter socket using optional adapter available separately.
