Bush_84 when I built my TBH I had some pieces of 4x4's, so it has those or the legs. Bottom of legs cut on an angle so to set flat. I try to level my hives side to side and front to back, using foundationless frames mostly. Also, some will say I am messing up and maybe but I have my hives under a metal roof. Don't have to worry about raining into hives, also have SBB's anyway. Good luck to yall
