Our local lumber store is closing and DH stopped in. He brought home a front door. But here is the thing DH is not handy at all. It is just the door no frame hardware or anything since it was a floor sample. Are we going to be able to hang this without a frame? HE was thinking he could just use the existing one, but I don't know. It is a real nice door and I am considering buying the window door panel too. But something tells me it won't work and we will be out $100. Please tell me I am wrong.
