Guest Posted April 29, 2006 Report Share Posted April 29, 2006 This door with it's CNC laser cut, dial-in low airflow control feature and it's matching precision cut and bent frame are the keys to superior airflow control which results in great temperature control. This is the Classic's door and frame. This is the OTB's door and frame. The metal work is flawless and does not require a gasket to extinguish the coals when fully closed Quote Link to comment Share on other sites More sharing options...
