Lit. exposed ridge. While this ridge is not usually 
      visible from inside a structure because of the installation of a ceiling, it is 
      so named because it is the ridge placed below the hidden ridge in a hidden roof 
      frame. The two ridges may touch or be separated. Usually the kenshou munagi is exposed in part because it extends into the barge course and the bargeboards 
      are attached to it.
