When this one was purchased, the feet were not available. This comes with everything that was in the package when it was bought new, it spent a lot of it's life out in the sun in Southern Arizona so the wooden handle has seen better days, but it's still in one piece.
The measurements on the website are metric, if you want that in freedom units then it is about 5" outside diameter and about 30" long, only 25" are usable. We found it easiest to use the little pans to hold food while cooking, so those are included as they fit perfectly.
The big orange plug is used if you choose to not use the drawer.
