Is the prehung door knocked down for delivery or just the frame?
To prevent damage in shipping, We ship all of our prehung units knocked down and the frame requires reassembly on the site.
A prehung door has a frame and is hanging by its hinges when you purchase it. You obtain the entire package including the hardware you need to install the door. There are a few main parts to this type of entry door: jambs, hinges, sill, door shoe, and weather stripping.
