Hi Everyone!
The new models do have one vent which is secured to the base using a bolt and nut. This is for our new "controller vent" which accommodates the Smartfire, BBQ Guru and the older FlameBoss controllers. We have a few of these in stock, but will have some more arriving soon. The fitment of this controller vent does not affect the other 2 vents (riveted) they simply need to be in the closed position when using a controller.
