Probe Ports make running electronics into the smoker a little bit easier. Keep the cables from pinching in the door by stringing them through the probe ports. Probe ports are welded right into the smoker and must be ordered at the time of your new smoker. Probe Ports come standard on the same side as the air inlet which is on the right side, facing the front of the smoker. Each probe port comes with a cap that is powder coated to match your smoker.
