to lock it in frown you need have it in flex, then you need to block the header (about 1 foot high) in the middle and set the header down on it so the header goes into full frown then put one set of the locks in (I cant remember if its the outer set or inner set) then it will be locked that way and give you a few more inches of clearance under the adapter, and it doesnt look like its broken when its sitting on the transport........lol
