Thanks for the picture of what you need. I see your grill came with a special regulator that has an inlet for a 1-pound propane bottle and a quick connector on the other side. This unit is not something that we sell.
The closest thing we have to that is a MB Sturgis # 108072 Single-Stage Propane regulator with one inlet and one outlet which are both 1/4" Female NPT.
On inlet side you could attach the JR Products # 37207-30185 adapter which will attach to your 1 pound propane cylinder.
